New Mercedes SL 400 replaces SL 350

The new Mercedes SL 400 (pictured) replaces the old SL 350 It’s a little over two years since the latest Mercedes SL arrived, and Mercedes has now decided to add a little zest to sales by dropping the old SL 350 and replacing it with a new Mercedes SL 400. The new SL 400 gets its power from the new E400 which means a twin-turbo 3.0 litre V6 with 328bhp and 354 lb/ft of torque – 26bhp and 81 lb/ft more than the old SL 350 – enough to let the SL 400 scoot to 62 mph in 5.2 seconds – 0.7s better than the 350 -= and on to a limited top speed of 155 mph. The new SL 400 has to make do with Mercedes tried and tested 7-speed auto – despite a new 9-speed now being available in Mercedes’ arsenal – which gives the SL 400 official economy of 38.6 mpg and emissions of 172g/km – not that you’ll come close in the real world.

Mazda is adding a fuel-saving technology that harnesses wasted brake energy in the redesigned Mazda6 sedan due early next year. The approach uses regenerative braking to convert kinetic energy into electricity that is stored in a capacitor. The car later taps that capacitor to power the fuel pump, lights, audio, air conditioning and transmission and engine control systems.
