Tesla Model S outsells luxury competition

As if Tesla needed any more good news this month, first-quarter sales are in and the electric Model S outsold the Mercedes S-class, Audi A8 and BMW 7-series, according to “CNN Money.” In the first three months of 2013, Tesla sold 4,750 sedans while Mercedes sold 3,077 of the S-class, BMW sold 2,338 of the 7-series and Audi sent 1,462 A8s out of the dealership. The Model S does have its sticker price going for it. The base model can be had for $69,900 -- possibly less with tax incentives -- while the cheapest S-class goes for $93,255, the 7-series for $74,525 and the A8 for $73,095.

Citroen C5 Airscape concept

Following the C-Airlounge of 2003, the C-Airdream of 2005 and the C-Airplay of 2006, is the C5 Airscape. Due to make its international debut at the Frankfurt Motor Show next month, this new Citroen concept acts as a spoiler for the forthcoming upper-medium C5 replacement dues soon. Unlike the forthcoming production car, the concept is a four seat coupe cabriolet which is aiming to show a new level of premium quality for the brand.
