Diesel joins Porsche Panamera lineup

Porsche has put forward some eye-catching fuel-economy figures for the Panamera diesel--although we may never see the car in the United States. Set to go on sale across Europe in August, the four-door is claimed to return a combined city/highway driving fuel economy of 36.2 mpg in standard guise under European testing procedures. When fitted with optional low-rolling-resistance tires, the fuel economy climbs to 37.3 mpg on the European test--a figure that gives the Panamera diesel a theoretical range of 800 miles on its 21-gallon fuel tank.

BMW 135is coupe and 135is convertible available for order

BMW announced that it will expand its 1-series lineup with the addition of the 2013 BMW 135is coupe and 135is convertible. The enthusiast-oriented 135is models will be powered by BMW's TwinPower 3.0-liter I6 engine that will produce 320 hp and 317 lb-ft of torque after factory tuning. That's a 20-hp and 17-lb-ft increase over the 2012 135i, but BMW claims that the vehicles will maintain both the fuel-economy and emissions ratings of the 135i.

Vauxhall Mokka SUV price from £16,995

The sub-comp[act SUV Vauxhall Mokka is now on sale in the UK in three trim levels with a choice of three engines from £16,995. First customer cars in November 2012. The official debut for the Vauxhall Mokka (which retains the German spelling of 'Mocha' for its name) was the 2012 Geneva Motor Show in March, although by then we already knew what was on offer. That's because not only had Vauxhall / Opel divvied up photos of the Mokka in January, we'd also had the Buick Encore revealed in the States which is, to all intents and purposes, a Mokka with an Uncle Sam badge.
