Mercedes benefits from trick to 'pump up' front axle

Undertray of Mercedes F1 car, 2013


There is an initial suspicion why Mercedes is so much faster. The engine produces more power and the car more downforce. Who would have thought? Williams, Force India and Lotus have the same engines. With the same fuel. Compared to those teams the Mercedes generates higher downforce. Which is quite unlikely in the second year of aerodynamic formula.

That is the finding of Germany’s Auto Motor und Sport, arguing that main rival Ferrari is now almost level-pegging with the world champions in terms of horse power.

And as far as the chassis is concerned, rivals are now beginning to look more closely at how the 2015 Mercedes is often so much better.

Referring to Silverstone, and a detailed analysis based on GPS data in qualifying, Force India’s technical boss Andy Green said: “They killed everybody in the last corner particularly.

“Apparently they’re keeping the rear tyres in such good shape in the first part of the lap that they still have good grip in the final corners. For everyone else, the temperature is going up too much for that.”

Green said he has noticed a key difference with the front suspension settings of the Mercedes.

Auto Motor und Sport correspondent Michael Schmidt revealed that the suspicion is that the W06, by way of an unexplained trick, is able to be “pumped up” for the optimal balance between high and low-speed corners. (ThisisF1/GMM)
