Hennessey-tuned Ford GT does a 235.1-mph Texas two-step

A few times a year, some of the fastest and most powerful cars meet in Texas for an adrenaline-filled weekend of top-speed runs called the Texas Mile. The high-performance machines have one mile of arrow-straight runway to get the highest top speed at the one-mile marker. It was the right mix of conditions for Mark Heidaker and Sean Kennedy, who drove their twin-turbocharged Ford GT to a top speed of 235.1 mph down the runway into a decent headwind of 20 mph.

'Smartest' UK drivers revealed

DRIVERS aged 50-65 from the Midlands have been judged to be Britain’s 'smartest' – displaying the most fuel efficient and safe driving behaviours – while people aged 18-30 from Wales and the South West are more like driving dunces, new research claims. Youngsters in the north of England are the nation’s smartest young drivers, but overall older drivers reign supreme on the road. The Shell FuelSave Smarter Driving research ranked young (aged 18-30) and older motorists (aged 50-65) on their ‘smart’ and ‘not-smart’ driving behaviours towards fuel efficiency and safety – everything from smooth driving to wearing appropriate footwear behind the wheel.

Porsche says Panamera avoids gas-guzzler tax

Few expenses were spared in conceiving the Porsche Panamera, but consumers will avoid at least one cost of ownership: the ignominious gas-guzzler tax. Porsche has announced ratings for the 2010 sedan; it will get a combined figure of 18 mpg or 19 mpg from the EPA, depending on the model. This means Porsche’s four-door foray will avoid a fairly substantial cost of ownership--a tax of up to $7,700 is levied on the most prolific guzzlers.
