Porsche says Panamera avoids gas-guzzler tax

Thu, 10 Sep 2009

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.

How Chevrolet plans to double sales in Europe

Wed, 01 Dec 2010

Chevrolet is planning to double European sales inside five years - and the new Orlando MPV and ground-breaking Chevrolet Volt are just two examples of how GM's budget brand plans to reach new customers. We often hear how up-and-coming brands hope to perform sales miracles, and the harsh truth is there's not the space for all of them to be proved right. But there is enough momentum behind Chevrolet to pay attention to this particular claim.

Mercedes SLS AMG Electric Drive sets Nurburgring production EV record

Sun, 09 Jun 2013

The Mercedes SLS AMG ED (pictured) set a new EV lap record at the Nurburgring Just as Audi decides that the R8 e-Tron isn’t a production viable option, Mercedes decides to prove there is potential for electric cars at the very high end. The Mercedes SLS AMG Electric Drive has been to the Nurburgring and set a new lap record for a production electric car of just 7 minutes 55 seconds. The SLS AMG ED, which goes on sale very soon at more than £300k, may weigh a chunk more than a regular SLS (550kg more), but it gets plenty of help from its four electric motors – one at each corner – to overcome the weight of its batteries with 751bhp and 737lb/ft of torque on hand.
