The Saleen S7 - The Airplane of Cars 2010
Kamis, 11 Februari 2010
The Saleen S7 is one of the most amazing cars now days. This car not only looks nice, but is also one of the highest performing cars on the road. The S7 has 750 hp (horse powers) and this power is achieved with a engine that is only 7 liters, something American car manufacturers can only dream about. Here is a list of its full specks taken from the Saleen website www.saleen.com

Whit these specks it is not surprising that the S7's top speed is 248 mph. Just to give you an idea of how fast that is I made a little comparison. The average takeoff speed for the commercial airplane Boeing 737 is 180 mph (source: http://www.aerospaceweb.org/question/performance/q0088.shtml) check it if you don't believe me. So this car is basically a airplane on the ground. Actually it is faster then a airplane on the ground, if it had wings it would be an airplane.
This is a nice car with some serious performance, but its not for anybody, as you might have figured out already. The price for a brand new Saleen S7 is about $ 555, 000., so you might want to brake a lot of piggy banks before you could afford one.
