One Lap of the Web: Famous Porsches at auction, Smokey the Aventador and classic snow cars

Here's a tip: If you're going to have a rev battle with a collection of Lamborghini Aventador supercars, keep clear of flammable foliage. Better yet, don't participate in something lame like a rev battle.

New entry-level Caterham Seven to cost under £17k

The new entry-level, sub-£17k Caterham Seven If there’s one thing you know about the Caterham Seven – Caterham’s recreation of Colin Chapman’s iconic Lotus Seven – it’s that it’s not b exactly laden with fripperies and heavy technology.

But Caterham say the new Seven will be probably the most fuel efficient car they produce with a new EU-6 compliant engine providing accessible fun for ‘under £17k’.

New Mercedes S-Class Plug-in Hybrid to debut at Frankfurt Motor Show

The new Mercedes S-Class (pictured) will arrive with a plug-in hybrid version in September We’ve known Mercedes were planning a plug-in hybrid version of the new S-Class as far back as 2009, and it now appears it will debut – as a 2014 model – at the 2013 Frankfurt Motor Show in September. When Mercedes revealed the Vision S500 Plug-in Hybrid Concept at Frankfurt in 2009, they had fitted it with a V6 petrol engine mated to a 44kw motor and a bank of lithium-ion batteries, and promised the hybrid S-Class would do 90mpg, have emissions of under 75g/km and manage 18 miles in EV mode. That means the hybrid S-Class would have performance comparable to the V8 petrol-engined S500 but attract no BIK or VED in the UK.
