Chevrolet Volt leads satisfaction survey

The Chevrolet Volt plug-in hybrid has topped Consumer Reports' latest owner-satisfaction survey after its first year on the market. The magazine said 93 percent of respondents who own a Volt said they would definitely purchase one again, making it the highest-rated car in the annual poll. Two second-place finishers, the V8-powered Dodge Challenger and the Porsche 911, drew the most-favorable grade from 91 percent of buyers.

Rolls-Royce debuts Ghost Series II at Geneva motor show

The Rolls-Royce Ghost has been with us for five years, and for 2015 the company has treated the sedan to a number of design tweaks inside and out, and has brought the refreshed Series II Ghost to the Geneva Motor Show this week.

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.
