Design Development: Kumho Epoch concept

The Epoch project is a concept you wouldn't normally expect from a tire manufacturer. Inspired by the company's success in this year's Le Mans 24 hour race, Kumho decided to employ its conceptual abilities to create their version of an environmentally-friendly Le Mans car of the future. Designed around innovative tire technology, the 'blue sky' Epoch eco-friendly racing car is the first in a series of concept vehicles set to be developed by Kumho over the next few years.

Mercedes C 63 AMG Edition 507: Price from £66,960

Available as Saloon, Estate or Coupe, the C 63 AMG Edition 507 will cost from £66,960 (for the saloon) and £68,160 (for the estate and coupe), or at least it will until you start to bother the options list. But for the base price you do get a fair bit already, with the AMG Drivers Pack as standard – which gives you extra horses (500bhp) and a higher top speed (174mph) and a free day out at an AMG BASIC Training Power and Passion Event so you can learn to drive your new C63 properly. As well as the extra power and freebie outing, you also get a selection of cosmetic and equipment teaks to the standard C 63 AMG including 19″ AMG Cross-Spoke alloys, composite brakes with red brake callipers, AMG bonnet with power dome and gloss black air vents and gloss black highlights for stuff like the mirrors and grill.
