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.

2011 Audi R8 GT, an AW first look

Three years after it burst onto the supercar scene, Audi has unveiled a hard-core version of its R8 called the GT. Based on the existing mid-engine R8 V10 and incorporating aerodynamic, weight-saving and mechanical developments used by the company's R8 LMS GT3 race car, Ingolstadt will build just 333 copies of the new 560-hp four-wheel-drive performance flagship. Pricing has not yet been revealed, but given the extent of the changes to the new two-seater, buyers should expect a hefty premium over the R8 V10's $147,000 price tag when the GT goes on sale in North America.

Planning continues for driverless cars

OFFICIALS in California have been looking to the future as they bid to legislate for the arrival of hi-tech driver-less cars.

The latest talks on the matter among roads officials focused on how the vehicles will record actions so the data can be used to reconstruct an accident in an effort to trace the cause.
