New details on Mercedes' Porsche 911 fighter

Mercedes-Benz's AMG performance-car division is forging ahead with development of its new twin-turbocharged 4.0-liter V8 powered sports car, nine months before it is scheduled to be revealed at the 2014 German Grand Prix. Known to insiders by its code name, “C190” the two-seat coupe has been conceived to follow in the wheel tracks of the four-year-old SLS at the head of the German carmaker's lineup, aiming to challenge the heady performance and everyday driving appeal of the latest Porsche 911 Turbo at a price that insiders suggest will be in the region of $160,000 when North American sales begin in early 2015. Originally, AMG's new front-engined sports car was tipped to revive the iconic SLC name first used by the SL coupe back in 1971.

New Mercedes A Class: A 180 BlueEFFICIENCY Edition models launch

Mercedes are launching two new eco versions of the new A Class – the A 180 CDI BlueEFFICIENCY Edition and A 180 BlueEFFICIENCY Edition. Mercedes has had a play with the aerodynamics on the new A Class to lower the Cd value from an already very low 0.27 to 0.26 by partially covering the upper section of the radiator grill, adding aerodynamically shaped spring link coverings that improve the flow of air along the underbody at the rear axle and lowering the suspension by 15mm. Mercedes has also tweaked the generator management for more efficiency and had a play with the gearbox to make the ratios longer (which will help economy, but won’t do much for responsiveness).
