Now the discerning customer has the opportunity to enjoy the unique high-performance character of a BMW M car also in the segment of BMW X models: The BMW X5 M and the BMW X6 M are the first all-wheel-drive models to offer the supreme performance, dynamic driving features, athletic design, and premium quality of a typical BMW M Car.

Both models are powered by a newly developed V8 high-performance engine delivering 408 kW/555 hp at an engine speed range between of 6,000 rpm from an engine capacity of 4,395 cc. The new M TwinPower Turbo engine is indeed the world's first power unit with a common exhaust manifold encompassing both rows of cylinders and featuring Twin Scroll Twin Turbo Technology.

BMW's intelligent xDrive all-wheel-drive system is naturally geared to the specific power and performance characteristics of the BMW X5 M and the BMW X6 M, just like Dynamic Performance Control also standard on both models. Interacting with the cars' special M suspension including Adaptive Drive and the newly developed Servotronic power steering, this ensures the driving behaviour so characteristic of a BMW M Car, combining unique driving stability with precisely controlled steering qualities all the way to the highest level of driving dynamics.

The BMW X5 M and the BMW X6 M set new standards in this segment of high-performance models in terms of acceleration, lateral dynamics, steering behaviour, stopping power, and efficiency. Both models accelerate to 100 km/h from a standstill in 4.7 seconds and stand out not only through the truly impressive delivery of power by the V8 turbo engine providing maximum torque of 680 Newton-metres or 501 lb-ft in the broad speed range between 1,500 and 5, 650 rpm, but also through the likewise smooth and consistent build-up of lateral forces meeting the highest requirements and the most dynamic level of performance in bends.

The exclusive character of both the BMW X5 M and the BMW X6 M results to a large extent from a level of driving performance never seen before even in this particular segment. Both models offer the ultimate in their segment in every respect, providing performance and dynamic driving reserves quite unique versus the competition and ensuring an experience of unlimited supremacy in everyday traffic.

Design: features typical of BMW M for supreme dynamics and exclusivity.
The truly outstanding potential of both models comes out clearly in their looks and design, their joint DNA borne out by supreme performance on the road presented convincingly by the common design of the front end with its large air intakes.

The engine compartment lid, the front air dam and the headlight graphics carried over from the BMW X6 are identical in both cases. The proportions of the two cars, on the other hand, clearly differ through the variability of the BMW X5 M Sports Activity Vehicle as opposed to the dynamic qualities of the BMW X6 M Sports Activity Coupé.

Both the BMW X5 M and the BMW X6 M feature special gill intakes in the front side panels tailored to each model as well as individually designed 20-inch light-alloy rims.
The signs of distinction so typical of BMW M are likewise presented in individual style at the rear, in both cases confirming the outstanding dynamism of each model: The rear air dam on the BMW X6 M demonstrates particularly powerful presence, while the two dual tailpipes in the exhaust system surrounded in both cases by the rear air dam are again typical of BMW's M philosophy.

Compared with the "regular" BMW X5 and the BMW X6, the share of black plastic surfaces around the lower section of the body is reduced on both new models, giving even greater emphasis to the road going-orientation of the BMW X5 M and the BMW X6 M. Particularly the body elements fulfilling major functions in terms of aerodynamics and the flow of cooling air are clearly accentuated on both models.

Beyond these common features, both of these all-wheel-drive high-performance sports cars stand out clearly as unique models in their own right: The BMW X5 M clearly boasts its superior power and exclusivity at very first sight, while the BMW X6 M, in its unique design, alludes to fascinating driving dynamics and the car's athletic charisma.
The M TwinPower Turbo: Twin Scroll Twin Turbo Technology with a joint exhaust manifold for both rows of cylinders making its debut in the market.

Power and performance typical of BMW M is delivered by the power unit in both the BMW X5 M and the BMW X6 M by a new design and construction principle: The new M TwinPower Turbo with Twin Scroll Twin Turbo Technology and the exhaust manifold extending over both rows of cylinders patented by BMW offer absolutely extreme response and spontaneity, a linear build-up of engine power, and an unusually consistent torque curve.

The two turbochargers are positioned together with the catalytic converters in the V-section between the two rows of cylinders. The position of the intake and exhaust ducts provided in this way serves to reduce the length of the pipes and manifolds and increase their cross-section, with pressure losses on the exhaust side being significantly minimised in the process.
The joint flow of exhaust gas provided by the common manifold system connecting two cylinders at a time also ensures optimum gas throughput. The separation of exhaust flow is continued until the exhaust gas reaches the turbine wheel, building up ongoing pressure on the two Twin Scroll Turbochargers not impaired by any kind of counter-pressure.
With maximum charge pressure amounting to 1.5 bar, the use of Twin Scroll Twin Turbo Technology with its inter-cylinder exhaust manifold makes unique use of the turbocharging potential.

Immediate, direct response to the gas pedal and truly exceptional pulling force from the engine starting at low speeds and continuing consistently to the highest load level characterise the new M TwinPower Turbo from BMW M GmbH. The truly impressive development of power ensured in this way is accompanied by fascinating engine sound accentuating the fast-revving engine characteristics and the linear build-up of power by a supreme acoustic effect typical of a BMW M Car.
Reflecting the superior power of the engine, the V8 power unit comes with a cooling system developed specifically for the two new models. One special feature in this context is the indirect intercooling effect serving to optimise performance under particularly dynamic driving conditions.
The new M TwinPower Turbo develops its outstanding output and performance with equally outstanding efficiency. In addition to direct ¬High Precision Injection, both the BMW X5 M and the BMW X6 M are equipped with a wide range of technologies from BMW ¬EfficientDynamics. Apart from Brake Energy Regeneration, these also include on-demand control of the electrical fuel pump, a detectable a/c compressor, as well as a volume flow-controlled supply of hydraulic fluid to the anti-roll system also operating specifically on demand.
Both models offer average fuel consumption in the EU test cycle of 13.9 litres/ 100 kilometres, equal to 20.3 mpg imp. Their CO2 rating is 325 grams per kilometre. And last but not least, the engine naturally fulfils all the requirements of the US LEV II standard as well as the EU5 requirements in Europe.

M Sports Automatic with electronic gear selector lever and shift paddles on the steering wheel.
Featured for the first time on a BMW M Model, the six-speed automatic transmission enhances the high-performance character of the BMW X5 M and the BMW X6 M through its spontaneous gearshift, direct connection to the engine, and the high standard of shift comfort. The new M Sports Automatic is controlled by an electronic gear selector lever on the centre console and offers the driver not only the D Mode, but also an S and M Mode for an even more sporting gearshift.
Aluminium gearshift paddles on the steering wheel exclusive to BMW M allow a manual gearshift significantly shortening gearshift times by the new technology reducing torque in the transmission through the deactivation of individual cylinders.

This significantly enhances the sporting character of the car, the gear in mesh being held in position in the M Mode up to maximum engine speed in order to give the driver optimum control of his vehicle also under the most dynamic driving conditions. In other words, the transmission does not shift up automatically at a certain engine speed in this mode.
A further option in the M Mode is to activate the Launch Control function enabling the driver to accelerate from a standstill with maximum performance: With the driver pressing the gas pedal fully down, M Sports Automatic shifts gears automatically at the ideal point and with optimum wheel spin control. An aluminium oil sump again exclusive to BMW M with a special finned or ribbed structure on the surface guarantees optimum cooling at all times even with an extremely sporting style of motoring.

BMW xDrive and Dynamic Performance Control with a special set-up for optimum dynamics.
The outstanding success of BMW's intelligent xDrive all-wheel-drive technology is based on the fact that the system not only improves traction on rough terrain, but also enhances driving dynamics on the road. Electronically controlled, variable power distribution to the front and rear axle prevents even the slightest tendency to over- or understeer right from the start, before DSC Dynamic Stability Control is even required to cut in.
Dynamic Performance Control presented for the first time in the BMW X6 and now featured also in the BMW X5 M and the BMW X6 M enhances driving stability in demanding situations. Variable distribution of drive power between the right and left rear wheel significantly improves steering precision and tracking stability at all speeds, with DSC being required to stabilise the vehicle only under high lateral acceleration.

Ultimately this offers the driver an unparalleled standard of dynamic performance, agility and traction re-defining all existing benchmarks in drivetrain and suspension technology.
In the BMW X5 M and the BMW X6 M the potentials of both systems are again used in that special style of BMW M, with the driver able to activate the M Dynamic Mode (MDM) by means of the DSC button on the centre console. This mode raises the DSC control thresholds for intervention in the brakes and the reduction of engine power and ensures the steering behaviour typical of BMW M by shifting the xDrive control features more to the rear wheels and interacting with Dynamic Performance Control in the process.

As a result, MDM allows maximum speeds in bends and on winding roads with the system cutting in very late when the vehicle reaches the absolute limit. Even under maximum load in the apex of a bend, therefore, the vehicle follows the steering with utmost precision, giving the driver very high speed when leaving the bend in the interest of optimum performance. And last but not least, the DSC-Off Mode may be activated at the touch of a button.
Special M suspension with Adaptive Drive featured as standard.

The suspension developed specifically for the BMW X5 M and the BMW X6 M with its double-track control arm front axle and Integral IV rear axle offers M-specific elastokinematics thanks to stiffer track control arm mounts and hydraulic tiebar mounts at the front as well as stiffer axle support mounts at the rear.

Both models come as standard with air suspension featuring self-levelling on the rear axle as well as Adaptive Drive with electronically controlled dampers (EDC) and active anti-roll stability. The special version of Adaptive Drive tailored to the requirements of BMW M also serves to lower the entire vehicle by 10 millimetres or 0.39" versus the "regular" BMW X5 and BMW X6 and incor¬porates stiffer carrier springs, modified auxiliary springs, three-way support mounts and damper control with reinforced connection to the body.

The special Servotronic steering developed for the BMW X5 M and the BMW X6 M provides individual steering assistance geared to the actual road speed of the vehicle. This allows comfortable parking manoeuvres with lower operating forces as well as exact feedback and a high standard of steering precision at higher speeds.

The degree of power assistance is defined by two control maps. Apart from the standard configuration, the driver is able, through the EDC and, respectively, the M Drive button, to call up the Sports Mode activating an uncompromisingly sporting control map with higher control forces for particularly dynamic driving conditions.

Changing from the Normal to the Sports Mode, the system alters not only the Servotronic control map, but also the damper setting, with the connection of the dampers to the body of the vehicle being significantly reinforced in the Sports Mode. In conjunction with anti-roll stability this allows an exceptionally high standard of linear lateral forces in dynamic bends and on fast, winding roads.
The high-performance brake system guarantees supreme stopping power and high resistance to fading under all conditions. The brakes come with four-piston fixed callipers at the front and swing callipers at the rear, combined in each case with inner-vented lightweight brake discs.
The BMW X5 M and the BMW X6 M are the only vehicles in their segment to come as standard with different-sized tyres front and rear, running in each case on 20-inch light-alloy rims. The choice of 275/40 R 20 tyres at the front and 315/35 R 20 tyres at the rear is a further result of the special set-up characteristic of both models, with the emphasis on rear-wheel power. The choice of this combination of tyre sizes ideal in terms of driving dynamics promotes both the exceptionally good transmission of power to the rear axle and the precise, exactly dosed steering behaviour of both models.

Dynamic performance according to the driver's personal choice and available at the touch of a button: the M Drive button on the steering wheel.
Apart from the DSC Mode and the specific set-up of both the dampers and the steering, the driver is also able to configure the set-up of the drivetrain on the BMW X5 M and the BMW X6 M according to his personal requirements. Activating the Power Mode which influences both engine and transmission control, the driver has the choice of both the Sports and Efficiency driving programs.

The Sports program allows precise dosage of engine power also under the most dynamic driving conditions specifically through the linear build-up of the power delivered.
The Efficiency program, in turn, shifts up gears at an early point in time not only to significantly reduce fuel consumption under practical driving conditions, but also to allow a relaxed style of motoring using the supreme torque and pulling force of the engine available from low engine speeds. The result, therefore, is an ideal combination of efficient motoring and supreme driving qualities.

In the M Drive menu the driver is able to pre-configure both the Power Mode and the set-up of DSC and EDC, the combination of settings chosen providing the set-up preferred by the driver under all conditions. The driver is even able to save his favourite set-up and subsequently retrieve it at any time simply by pressing the M Drive button on the steering wheel.
The M Drive menu is yet another specific M feature supplementing the vehicle, infotainment, navigation, air conditioning and communication functions already controlled by BMW iDrive. Both the BMW X5 M and the BMW X6 M are equipped with the latest generation of iDrive and come as an option with a Head-Up Display again specific to BMW M. Indeed, this function even enables the driver to vary the type and scope of the data projected on to the windscreen in accordance with the M Drive menu.

M-specific cockpit and sophisticated driver assistance systems for even greater supremacy at the wheel.

The philosophy so typical of BMW M naturally continues into the design and configuration of the driver's "workplace": Both of these all-wheel-drive high-performance sports cars come with a special M cockpit with the instrument cluster featuring a variable pre-warning field in the rev counter, specific vehicle function displays, and white display illumination. And both the BMW X5 M as well as the BMW X6 M boast M seats and an M leather steering wheel.
The driver's superior style of motoring is enhanced additionally by innovative driver assistance systems, both models fitted as standard with cruise control incorporating its own brake function. The wide range of optional features, in turn, includes Adaptive Headlights and a High-Beam Assistant.

Supplementing BMW Park Distance Control naturally featured as standard, there is also an optional back-up camera including its own very special Top View function.
The wide range of standard features includes electrical seat adjustment complete with a memory function and seat heating at the front, two-zone automatic air conditioning, extended Merino leather, a HiFi audio system with 12 loudspeakers and 230 Watt amplifier output, M entry trim, an M footrest, interior trim in brushed Aluminium Shadow on both models as well as a BMW Individual instrument panel finished in leather and automatic operation of the tailgate on the BMW X6 M. The optional comfort features available on both the BMW X5 M and the BMW X6 M include BMW's Professional navigation system, four-zone automatic air conditioning, active seat ventilation, full leather upholstery in Merino leather, a panorama glass roof on the BMW X5 M and an electrically operated glass roof on the BMW X6 M as well as the BMW Individual High End audio system.

Troca de Anéis - 11ª Parte

Se você ainda não leu a 1ª parte, 2ª parte, 3ª parte, 4ª parte, 5ª parte, 6ª parte, 7ª parte, 8ª parte, 9ª parte e 10ª parte de Troca de Anéis, pode ser que fique em duvidas no texto seguinte.

Deve-se sempre procurar instalar os anéis com um alicate apropriado ou outra ferramenta semelhante a fim de evitarem-se os problemas antes mencionados.


Instalação de um anel com o alicate apropriado.

Quanto à localização das pontas dos anéis, desde que não existam recomendações especificas do fabricante do motor e não havendo pinos ou outros dispositivos que fixem o anel em uma determinada posição no pistão, a experiência tem demonstrado que as mesmas poderão ficar em qualquer posição ao redor da circunferência do pistão.

Isto se justifica porque os anéis sem pino de fixação e sem mola movimentam-se em torno do pistão alterando a posição das pontas de um anel, tanto em relação ao pistão, como aos outros anéis.

O importante, no caso, é deixar-se as pontas dos anéis em posição diferente entre si de modo que dificilmente as folgas dos anéis venham a alinhar-se o que provocará consumo de óleo e passagem de gases para o cárter.

Uma localização das pontas dos anéis em um pistão de 4 canaletas, que poderá ser adotada, é mostrada na figura abaixo:


Posição de montagem dos anéis em um pistão de 4 canaletas.

Concluída a montagem os anéis e pistão devem se bem lubrificados com óleo limpo (de motor) a fim de garantir lubrificação suficiente ao cilindro nos primeiros instantes de funcionamento do motor e evitar a ocorrência de escoriações ou engripamento.

Verificações antes da montagem

Em seguida dos anéis nos pistões e para que o serviço possa trazer bons resultados, não devem ser esquecidas outras verificações prévias que são: o exame das bronzinas e substituição das que estiverem apresentando desgaste ou folga excessivos, a inspeção do virabrequim quanto a trincas e estados dos colos e as condições de desgaste dos mancais fixos e estado geral do bloco do motor.

Feitas essas verificações, monta-se o virabrequim no motor, atentando para que as folgas radiais e axiais e os apertos dos parafusos dos mancais estejam de acordo com as recomendações do fabricante e passa-se à limpeza dos cilindros.

Obs.: Maiores detalhes sobre o exame do bloco, virabrequim, bronzinas e outras partes do motor e sua retificação, bem como a montagem de camisas e outros componentes, estarão na “Retificação de Motores” que virá em postagens futuras.

Montagem do pistão no cilindro

O primeiro passo a ser dado é proceder uma cuidadosa limpeza dos cilindros, para retirar quaisquer impurezas presentes, principalmente resíduos de usinagem da crista ou abrasivos deixados durante o brunimento.

A limpeza dos cilindros

A execução de uma limpeza cuidadosa dos cilindros, antes de instalarem-se os pistões com anéis, é extremamente importante porque, se os mesmos não forem limpos, uma quantidade considerável de abrasivos permanecerá no motor. Esse material abrasivo desgastará rapidamente os anéis, as paredes dos cilindros e as superfícies de contato de todas as peças móveis e lubrificadas e o serviço deverá ser refeito em pouco tempo.

Assim sendo, limpe os cilindros meticulosamente, removendo o mais que for possível de depósitos abrasivos das paredes do cilindro.

Limpe, depois, cada cilindro com um pano embebido em óleo de motor e esfregue cuidadosamente com um pano limpo.


Limpe cuidadosamente os cilindros após o brunimento a fim de evitar um vida curta do motor.

Pepita essa operação três vezes (e até mais se for necessário), pois só uma não é suficiente. Continue limpando até que um pano branco e limpo não mostre mais sinais de impurezas quando passado no cilindro.

Nunca use gasolina, querosene ou detergente comerciais para limpar os cilindros após um brunimento. Os solventes dessa natureza não removem os abrasivos das paredes dos cilindros. Se os abrasivos não forem adequadamente retirados dos cilindros, ocorrerá um desgaste rápido do motor e dos anéis.

Montagem do cilindro

Uma vez feita a limpeza dos cilindros, temos agora condições de instalar os pistões no motor.
Por isso, é necessário o uso de uma ferramenta compressora de anéis para permitir a introdução do pistão no cilindro.


Uso da ferramenta compressora de anéis.

Sem essa ferramenta, o serviço, alem de tornar-se mais difícil, também poderá ficar de má qualidade, pois, quando se introduz o pistão no cilindro com os anéis não comprimidos, estes poderão chocar-se com as bordas do cilindro e ficar com rebarbas que irão riscar suas paredes.

Assim sendo, aplica-se essa ferramenta aos pistões (que já deverão estar com as respectivas bielas instaladas, na maioria dos casos) e introduzem-se os mesmos nos cilindros passando-se em seguida à colocação das bronzinas e capas de bielas.

Durante esta operação, que normalmente é feita com o virabrequim previamente instalado no motor, deve-se ter o cuidado de montar as bronzinas exatamente no mesmo lugar onde estavam antes de serem desmontadas (no caso de estarem sendo reaproveitadas) pois já se assentaram ou se amoldaram perfeitamente ao respectivo colo no virabrequim. Caso não seja tomado esse cuidado e as bronzinas forem misturadas poderão ocorrer problemas de folgas ou interferências excessivas entre as bronzinas e seus colos, sendo isto válido também para as bronzinas dos mancais fixos.

Outro cuidado a ser tomado, independente de serem bronzinas novas ou usadas, é o de seguirem-se sempre as recomendações do fabricante do motor com relação às folgas radiais e axiais e o aperto dado aos parafusos dos mancais fixos e das capas de bielas.

Mercedes-Benz SL63 AMG F1 Safety Car (2009)

Download Wallpaper Gallery(9)

The Official F1 Safety Car is always deployed whenever the safety of a race is threatened by accidents, adverse weather conditions or other hazardous situations. Sitting behind the wheel of the exceptional Mercedes-Benz SL63 AMG will be Bernd Mayländer (Germany, 37 years of age). After receiving instructions from the race management, the former DTM driver must go to the head of the Formula 1 field and safely guide the world's fastest racing drivers around the circuit. Fast lap times are a must for the Safety Car, because otherwise the Formula 1 engines would overheat - and their tyres and brakes would also cool down excessively.

As in 2008, the role of the Official F1 Safety Car is also being fulfilled during this year's new season by the Mercedes-Benz SL63 AMG. Its distinctive driving dynamics are a basic requirement for its challenging Formula 1 assignment: the AMG 6.3-litre V8 engine has a power output of 386 kW/525 hp, providing acceleration from zero to 100 km/h in 4.4 seconds. A newly developed AMG sport exhaust system with larger pipe diameter and special rear silencers allows the high-revving AMG naturally aspirated engine to breathe even more freely - and gives it an even sportier sound. Outstanding driving dynamics are guaranteed by the newly developed AMG SPEEDSHIFT MCT 7-speed sports transmission with column shift, which makes it possible to change gear in just 100 milliseconds.


Special coil-over suspension and cooling measures
Optimum racetrack performance is guaranteed thanks to the specially developed coil-over suspension, which can be customised to a specific racetrack by means of individual suspension setup configurations. The combination of 3-stage ESP® and rear-axle differential lock with 30 percent locking effect provides optimum traction in all weather conditions. In the interests of reliability even at tropical ambient temperatures, the vehicle incorporates large-size, additional coolers for engine oil, transmission oil, coolant and power steering.

Special cooling measures and heavy-duty composite braking system
The front and rear axles feature 19-inch extra-light AMG forged light-alloy wheels. The 8.5-inch (front) and 9.5-inch (rear) rims are fitted with tyres of size 255/35 and 285/30, respectively. The design of the rims, with their intricately styled double spokes, optimizes both the cooling of the highly stressed braking system and the specially engineered cooling-air flow. Optimum fatigue resistance and best-possible deceleration values are among the self-evident characteristics of the AMG high-performance braking system, which is equipped all round with internally ventilated composite brake discs. The front axle is fitted with six-piston fixed callipers and discs of size 390 x 36 millimetres, while the rear axle features four-piston fixed callipers with brake discs of size 360 x 26 millimetres.

220 kilograms lighter than the series-production vehicle thanks to targeted lightweight design measures

Thanks to targeted lightweight design measures, the Mercedes-Benz SL63 AMG F1 Safety Car weighs in lighter than its series-production counterpart - and this is despite additional cooling measures, lighting system and communications equipment. The engine bonnet, front and rear aprons, front wings and luggage compartment lid are produced from carbon-fibre-reinforced plastic, a material that has been tried and tested in motorsports. Since the Safety Car is always driven with its top up, the vario roof has also been dispensed with. The result is a weight reduction of 220 kilograms, with the Safety Car weighing in at just 1750 kilograms (with a full tank and without occupants).

Apart from its special roof attachments and F1 logos, the Mercedes-Benz SL63 AMG F1 Safety Car is distinguished from the standard-production AMG high-performance roadster by a front apron with larger cooling-air openings. A prominent feature at the rear of the vehicle is the modified diffuser insert in the rear apron, which incorporates the active rear-axle cooling, this compensating for temperature peaks in the highly stressed differential housing. The white LED flashlights in the headlamps and tail lamps are always in operation whenever the vehicle is in use and have a neutral signalling function. The number plate with Safety Car lettering on the rear is illuminated by means of almost 700 LEDs and guarantees even greater safety, particularly in rain or darkness.

Interior with undiluted motorsport flair
The inside of the Safety Car is dominated by an atmosphere of undiluted motorsport flair. The workplaces of Bernd Mayländer and his co-driver feature two AMG sports bucket seats with 4-point seatbelts, trim parts in real carbon fibre, black leather appointments and the AMG performance steering wheel with its 365-millimetre steering wheel rim, flat underside and AMG aluminium shift paddles. The centre console is equipped with two monitors to enable the crew of the Safety Car to supervise the action on the racetrack, while the two-way radio system allows them to remain in contact with the race management.
