Mercedes SLK55 AMG (2011) at the Frankfurt motor show

Mon, 12 Sep 2011

This is Merc's hot rod drop-top, the SLK55 AMG. It's the most powerful SLK of all time, because under that bonnet and behind that three-pointed star is a new 5.5-litre V8 producing 416bhp. So the badge finally corresponds to the engine size?

Gordon Murray Design T25 (2010) first official pictures

Mon, 28 Jun 2010

This is Gordon Murray's new city car, the T25. Although previously scooped by CAR as long as two years ago, these are the first official pictures of the Gordon Murray Design T25 that its makers claim will revolutionise car design, manufacturing and even the way we drive. He did indeed design the seminal McLaren F1 and still hopes to build another one, but in the meantime the T25 is designed for the more humble motorist.  Gordon Murray Design is keen to promote itself as a leader in downsizing, both in terms of the physical footprint of the car and engine size.

Bungling thief caught after stealing hire car's steering wheel

Thu, 27 Mar 2014

A DIM-WITTED criminal has been convicted of theft after stealing parts of a brand new Audi A3 hire car and replacing them with old bits taken from his much older Audi S3. Alexander Keating, a 23-year-old former bodyshop technician who lost his job following the conviction, stole parts as obvious as the steering wheel and gear knob from the A3 that his mum had hired after damaging her car in an accident. Keating foolishly believed no one would notice the battered old steering wheel on the otherwise shiny, new car, but sure enough the mismatched parts were spotted and the hapless bungler was caught by the car hire firm’s bespoke anti-fraud team Asset Protection Unit (APU).
