The outside of the McLaren is incredibly futuristic, to say the least. On the inside, with the help of an onboard computer, the car is basically alive - with the ability to adjust its own spoiler height and angle of elevation.
The SLR is surprisingly fuel efficient for a supercar, though it weighs more than others in the class like the Lamborghini. The McLaren receives 16 miles per gallon, which might not seem like a lot but still, it's good compared to the competition.
The car's performance is helped along with a lightweight carbon-fiber body and a classic, aerodynamic racing design. The exterior of the car is beautiful, featuring a fully retractable soft top, gull-wing doors, and large chrome exhaust side-pipes. Critics consistently rank the SLR high because of the power it's able to put out for a car that could sell on looks alone.
Under the hood, the SLR boasts a hand-built 5.4 liter supercharged, SOHC V8. The engine is unchanged over the years, and consistently puts out the impressive 617 horsepower. The McLaren can go from 0 to 60 in 3.8 seconds and has a max top speed of 208mph.
It's so easy to forget that this supercar is still also a Mercedes-Benz; and that would explain the astonishingly high luxury rating for a car which, for all intents and purposes, is built for pure muscle and speed. The SLR comes with every bit of luxury you'd expect to find in any Benz.
Anyone lucky enough to ride in this car will enjoy plush seats completely covered in suede, a state-of-the-art Bose surround sound stereo system, updated navigation systems, adaptive cruise control features, and the dual-zone climate control features. Mercedes proves that even muscle cars can benefit from a soft side.
The 2009 edition of the McLaren has yet to be crash tested, but the line generally is that it is one of the safest supercars available. The carbon-fiber body is extremely light and strong, and the steel-reinforced A-pillars and fixed rollover bars protect the occupants of the car in case of a crash.
More modern technology is used as well, including knee-protecting airbags, automated stability control, and the braking system which is composed of carbon ceramic to improve stopping power and decrease heat and wear.
