2014 Mercedes S65 AMG spied undisguised (video)

The 2014 Mercedes S65 AMG (Pictured) spied on video ahead of an LA debut We’ve already had the new Mercedes S-Class revealed and its everyday performance version – the new Mercedes S63 AMG – has been unveiled too. But there’s one more S-Class to come – the 2014 Mercedes S65 AMG. We’re expecting the S65 AMG to arrive at the Los Angeles Auto Show later in 2013, but it looks like Mercedes are readying some promotional videos for their new range-topping powerplant in the S65, with a completely undisguised car caught on video.

Porsche 911 Speedster arrives +Video

The Porsche 911 Speedster will debut at Paris We were beginning to think that Porsche would keep the Porsche 911 Speedster under wraps until the Paris Motor Show kicks off proper next week. But in the end they couldn’t resist unveiling the big brother to the Porsche Boxster Spyder (a Speedster in all but name) with a week to go ’til Paris. We’ve been expecting the first 911 Speedster from Porsche in almost a generation since we first reported back in June that we would see the Porsche 911 Speedster rocking in for Paris, along with the 911 GTS.

Renault Twin’Run gets 316bhp & pays homage to the Renault 5 Turbo

The Twin’Run is an extreme version of the next Twingo and manages to pay homage to the old Renault 5, with a thumping great V6 bolted in the middle and pumping out 316bhp and 280lb/ft of torque, enough to get to 62mph in 4.5 seconds and on to 155mph. The Nissan-sourced V6 gets mated to a SADEV six-speed sequential gearbox and comes with a limited slip diff to stop the tyres burning off when the going gets brisk. As well as endowing the Twin’Run with lots of power, Renault has also kept weight down to 950kg by using a tubular chassis, glass-polyester composite for the bodywork, lumps of carbon fibre and not a hugely laden interior.
