From GMMAccording to the German magazine Auto Motor und Sport , Formula 1 team McLaren's 2008 car is now benefiting from the superior performance of its Mercedes-Benz engine.The report claims that recent chassis improvements, including the Honda and BMW Sauber-like nose wings that debuted in Hungary, are allowing the car to perform more efficiently through the air.Rival teams believe Mercedes' V8 engine is producing about 25 horsepower more than any other 2.4 litre unit on the grid."If those numbers are right, then an advantage of 25 horsepower with the same air resistance brings a benefit of four tenths (per lap)," BMW's technical chief Willy Rampf commented.McLaren's MP4-23 has won the last three grands prix in the hands of Lewis Hamilton and Heikki Kovalainen.
