Tiremakers offer new tread designs and compounds for winter
Wed, 17 Nov 2010When preparing your vehicle for winter, most people think about getting the battery tested, installing new wiper blades and having plenty of windshield-washer fluid on hand. Those are all good habits. But if you live in a cold-weather part of the country, installing a dedicated set of winter tires is another thing you should consider.
VW Touareg BlueMotion hits the UK
Fri, 12 Jun 2009Volkswagen has announced the VW Touareg BlueMotion for the UK Offering improved economy and lower emissions, the Touareg BlueMotion manages to drop in to a lower Co2 band by emitting 219g/km (a reduction from 244g/km on the V6 TDi) and it delivers 34mpg as opposed to 30.4mpg on the V7 TDi. These improvements have been achieved by the usual ECU tweaking, low rolling resistance tyres, some aerodynamic tweaks and a lower ride height (exactly the same sort of stuff that Ford has done on the EConetic range). And the penalty for the lower emissions and better economy is very slight, with the Touareg BlueMotion still managing the 0-60mph in 8.5 seconds and a top speed of 126mph.
