Aston Martin Hybrid Hydrogen Rapide S race car revealed

The new Aston Martin Rapide S was revealed in January, and now Aston Martin are taking the Rapide S racing, but with a twist – it’s going to be able to run on hydrogen. Aston Martin has been working with hydrogen experts Alset Global and have developed a twin turbo version of their 6.0 litre V12 that can run on petrol, gaseous hydrogen or a blend of both and the plan is to run the Rapide S at the 24 Hours of Nürburgring next month with at least one lap run on hydrogen alone. The hydrogen system in the Rapide S (which AM are calling a hybrid, but it’s only a hybrid in the sense it uses two fuels, not that it uses electric motors) has a hydrogen fuel rail, storage tanks and its won engine management system to control combustion.

New Mercedes A45 AMG has 105 years of 4WD on its side

With the new Mercedes A45 AMG on the horizon – complete with 4WD – Mercedes chart the history of all wheel drive on their vehicles.

But the history of 4WD goes back, certainly in the case of Mercedes, a surprising 105 years when Daimler built the Dernburg-Wagen, a 4WD vehicle that not only got all-wheel drive but all wheel steering too.

Fiat 500 Coupe Zagato gets green light

Fiat 500 Coupe Zagato to go in to production When we counted up the number of cars that appeared at the Geneva Motor Show this year it came to over 200. Not all the cars were new arrivals and many were a bit dull. But one we did miss was this rather appealing Concept Fiat 500 – the Fiat 500 Coupe Zagato – which is not just a Zagato take on the 500 but an entirely new Fiat 500 shape – the 500 Coupe.
