Mercedes Benz SLR vs. Bugatti Veyron
The Mercedes-Benz SLR McLaren is an Anglo-German sports car jointly
developed by Mercedes-Benz and McLaren Automotive, built jointly in
Portsmouth and the McLaren Technology Centre in Woking, Surrey, England.
Daimler AG, owner of Mercedes-Benz, also owns 40% of the McLaren Group.
Due to the presence of the automatic gear box, front mid-engined
arrangement and its driving characteristics lead some commentators to
classify the SLR McLaren as a GT whose rivals can be considered to be e.g.
the Aston Martin V12 Vanquish and Ferrari 599 GTB.
It is the fastest automatic transmission car in the world. SLR stands for
"Sport, Leicht, Rennsport" (sport, light, racing). Mercedes-Benz has stated
that they will build 3500 SLRs in a span of 7 years, with an annual
production of only 500 cars. The car's base price is GB£300,000 (approx.
US$495,000 or €475,000, c. 2007).
The Mercedes-Benz SLR McLaren is inspired by the Mercedes-Benz 300 SLR of
1955, based on the W196 F1 car, yet named after the road-going 300SL
Gullwing. On 4 April 2008, Mercedes announced they will cease production of
the SLR. The last of the coupes rolled off the production line at the end
of 2007 and the roadster version is due to be discontinued in early 2009.
The brake discs are carbon-ceramic and provide better stopping power and
fade resistance than steel discs when operating under ideal working
temperature. Mercedes-Benz claims these discs are fade resistant to
1200°C. The front discs are internally vented and 370 mm in diameter. 8
piston calipers are used. Rear discs are 360 mm in diameter with 4 piston
calipers. During wet conditions the calipers automatically skim the surface
of the disks to keep them dry.
To improve braking performance there is an automatic air brake, when
engaged the rear elevation angle of the rear spoiler is set to 65 degrees.
The additional rear downforce in addition to the markedly increased
aerodynamic drag increases peak deceleration ~25%.
The SLR features active aerodynamics; there is a spoiler mounted on the
rear integral air brake flap. The spoiler increases downforce depending on
its angle of elevation (angle of attack). At speeds above 95 km/h the
spoiler/brake automatically raises to 10 degrees (15 in 722 edition), when
demanded via the driver's switch, the elevation can be increased to 30
degrees (35 in 722 version) for increased rear downforce, at the cost of
increased steady state drag.
The SLR McLaren sports a hand-built 5.4-litre, supercharged V8 engine.
The SLR sports a 232-kilogram (512 lb), hand-built, 5.4-litre (5439
cc/331.9 cu in), supercharged, all-aluminum, SOHC V8 engine. The cylinders
are angled at 90 degrees with three valves per cylinder and lubricated via
a dry sump system. The compression ratio is 8.8:1 and the bore and stroke
is 97 millimetre (3.82 in) and 92 millimeters (3.62 in), respectively. The
Lysholm-type twin-screw Supercharger
produces 0.9 bar (13 psi) of Boost,
the turbine rotates at 23000 revolutions per minute, and the air is cooled
via two Intercoolers. The
engine generates a maximum power of 626 PS (617 hp/460 kW) at 6500
revolutions per minute and a maximum torque of 780 newton-metres (575
ft·lbf) at 3250 revolutions per minute. 2003 models were leaving showrooms
at 616 bhp (459 kW/625 PS) and now are slightly increased to 626 bhp (467
kW/635 PS) .
Unlike most of its contemporaries, its engine is front-mid mounted. McLaren
took the original concept car designed by Mercedes and moved the engine 1
metre (39.4 in) behind the front bumper, and around 50 centimetres (19.7
in) behind the front axle. They also optimized the design of the center
Benz v Bimmer: 2008 Mercedes C63 AMG vs. 2008 BMW M3 Sedan
There will be no Camaro
vs. Mustang death match
this week due to a distinct lack of Camaro, so can we interest you
instead in a muscle-car comparison test? Here we have two classic
nameplates, each with a 400-horsepower V8 stuffed into a
smallish four-door body shell and powering only the rear wheels.
Naturally we're referring to those two paragons of modern muscle, the 2008
BMW M3 Sedan and the 2008 Mercedes-Benz C63 AMG.
Don't be confused by the German nameplates, the aura of high-tech
engineering and the rarefied price tags. The 2008 BMW M3 Sedan and 2008
Mercedes-Benz C63 AMG match up as naturally as any muscle cars on Woodward
Avenue during the 1960s.
