Mercedes-Benz SLR McLaren is a supercar that has creature comforts. Unlike
most supercars that sacrificed comfort for performance, SLR McLaren have the
best of both worlds. So before we talk about the SLR's performance, first let me
explain about its comfort. SLR McLaren, unlike any other supercars have
powerseats. You can adjust the position of your seat with a push of a button, it also
has power windows and power locks as well.
If you feel that the temperature
is warm you can turn-on the airconditioning system and play some
music on a top-shelf seven-speaker Bose sound system, and in
case you get lost there is also a navigation system to guide
you. For your safety you can find that the SLR McLaren have six
air bags protecting the driver and passenger alike from impact
in all eight directions. Since SLR McLaren was based on the
technology of the Formula One car shifting thumb switches are
also located at the steering wheel which adds up to your feel of
comfortable driving experience.
Talking about power, SLR McLaren
has a 332 cubic inch which is 5.5 liter V8 engine. This engine
was hand-built by AMG, a company that usually modifies
Mercedes-Benz street cars into full-fledged race cars. It has a
single overhead camshaft, both the cylinder block and head are
made from aluminum, and it has a compression rate of 8.8:1. SLR
McLaren has two intercoolers to cool-down the twin-screw Lysholm
supercharger which adds up to its horsepower. Similar to all
supercars including the Formula One, SLR McLaren has a dry-sump
lubricating system which allows the engine to be mounted lower,
dropping the car's center of gravity. All this accumulates to a
617 hp @ 6500 rpm, and 575 ft.-lbs. of torque @ 3250 rpm. From
all of its ingredients SLR McLaren has a top speed of 207.5 mph
and has a very quick acceleration of 0 to 60 mph at 3.8 seconds.
Unlike most supercars mounts
their engines behind the driver, the SLR McLaren is a
front-mounted engine which gives the car its distinctive shape.
The engine is mounted as far back in the compartment as
possible, sitting behind the front axle. That gives the SLR
nearly 50/50 front to rear weight distribution, a major factor
in the car's overall handling. It also has an advanced frame
with a monocoque carbon-fiber tub making up the main chassis and
sub-frames in the front and rear. The rear sub-frame is made
from aluminum. Tubes and pockets made of carbon fiber within the
frame are based on safety designs from McLaren's F1 efforts, and
absorb four times as much energy as steel in an impact.
The transmission which transfers
the power to the wheels is a five-speed "manumatic"
transmission. The driver can shift electronically at the push of
a button. An Electronic Stability Program (ESP) helps drivers
handle all that power by constantly monitoring traction,
adjusting torque, and selectively applying the brakes to prevent
the car from spinning out of control. The ESP system has both a
full setting and a setting that puts more control into the hands
of the driver, but it can't be turned off completely. Mercedes
feels that more than 600 horsepower is a bit much for even
experienced drivers to handle.
What keeps the SLR McLaren on the
road is Michelin Pilot Sport PS2 tires with front tires 245/35
ZR-19 96Y and rear tires 295/30 ZR-19 100Y, which are mounted to
19-inch cast aluminum asymmetric turbine wheels. Its stopping
power is a special ceramic disc brakes, manufactured for heat
resistance and strength, provide up to 1.3 Gs of stopping power
a 161-foot braking distance from 70 mph, and rack-and-pinion
steering system features a 40-foot turning radius. The rear
spoiler acts as an automatic air brake, raising up to a 65
degree angle to provide additional downforce and stability. It
drops back down for flat-out high-speed runs.
