Mercedes introduces illuminated three-pointed star [w/video]

Illuminated badges and emblems on cars aren't a new idea – those old enough to remember will recall the warm glow of the old Wolseley grille emblems – but in recent history they have been the reserve of concept cars and the aftermarket. Mercedes is set to restart the trend however as it begins to offer an LED-illuminated star as a dealer-fit option on the E–, GL–, M– and CLS–Class. We've started to see lighting spill out onto the exterior of concept cars for a while and this move is sure to have other OEMs and aftermarket firms alike following Mercedes' lead.

Koenigsegg Agera at Goodwood: Up close and personal

Koenigsegg Agera on the Goodwood hillclimb We have to confess that we have a huge soft spot for the creations of Christian von Koenigsegg. So when we knew that friend of Cars UK Tommy Wareham, purveyor of all things stunning on four wheels at SuperVettura, was taking the only Koenigsegg Agera in the UK to Goodwood we thought Claire’s Goodwood Odyssey should continue with a good poke round the Agera. Understandably, Tommy wasn’t going to let Claire – or anyone else – loose on the Agera up the hillclimb as it’s a customer’s car, but he did chuck Claire the keys for a good look round, the opportunity to grab a set of Agera photos (below), and the chance to dream… Beautifully finished and oozing carbon fibre from every pore, the Koenigsegg Agera is perhaps the ultimate bonkers supercar, at an equally bonkers price – just think of it as a million pound supercar; it’s close enough.

Mazda reveals Mazda2 EV with range-extender Wankel rotary engine

Mazda reveals Mazda2 EV with range-extender Wankel rotary engine It’s long seemed logical that a compact Wankel rotary engine – running at a constant speed – would be a great way of fitting electric cars with a range-extender option. Audi flirted with the idea of fitting the A1 e-tron with a Wankel engine a couple of years ago, but that got shelved. And Mazda – keepers of the Wankel flame – came up with the idea of a Wankel engine bolted in to an EV and powered by hydrogen last year, but it seems to0 have gone nowhere.
