Mazda to use regen brakes to boost fuel economy 5 to 10 percent

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.

2014 Mercedes S Class LIVE reveal

The new S Class (W222) gets a bit longer than the current S Class (by 20mm), a bit wider (28mm) and a bit lower (25mm) but the wheelbase of the standard S Class stays the same at 3035mm with the long wheelbase S Class getting an extra 130mm for extra sprawling room. There will be a variety of engines on offer in the new S Class (from parsimonious 4-cylinders to mighty V12s) but we’re expecting at launch that just three will be on offer – the S350 diesel with a 255bhp V6, the S400 with a 300bhp V6 petrol and the S500 with a 4.7 litre turbo petrol with 450bhp. In terms of styling, Mercedes appear to have taken away much of the bulbous look of the current S Class and replaced it with a more flowing shape, but one that’s still very much S Class.

Aston Martin V8 Vantage (2012) the Vantage S-inspired upgrade

This is Aston Martin’s new V8 Vantage, with a new gearbox, styling tweaks and chassis upgrades. You might think it looks little different than before – and that’s no bad thing – but Aston Martin claims the updates amount to ‘most comprehensive programme of enhancements’ since the 4.7-litre version of the V8 Vantage was launched in 2008. The new Aston Martin V8 Vantage will be unveiled at the Geneva motor show in March 2012, just in time to distract potential customers away from the new Porsche 911.  So what’s new about the new Aston Martin V8 Vantage?
