Aston Martin DB9: The TechnologiesAston Martin DB9 was based on a new chassis made of a great number of aluminium parts and components so that to decrease the automobile's weight and to make it more rigid, what is more, improved steerability was also the purpose to achieve. Aston Martin DB9 is provided with 450-horsepower V12 5.9-liter engine. Aston Martin DB9 does 0-100 km/h in 4.7 seconds although it weighs 1.7 tons, while its top speed makes up 300 km/h. The engine Aston Martin DB9 is provided with is flawless so as the automatic gearbox is. The gearbox has understeering switches and operates perfectly even when "D" mode is on. Aston Martin DB9 behaves perfectly when driving slowly but the car lacks rigidity and although that doesn't affect steerability it makes the roof tinkle when driving on a badly conditioned road. Naturally this doesn't happen when the road is smooth and it is perfectly quiet in the saloon then.
