Volvo V60 PHEV

Turns out, people want a highly efficient Volvo. The Swedish automaker originally was going to offer only 1,000 of its first production diesel plug-in hybrid (PHEV), the V60 PHEV, but now it is apparently having trouble keeping up with demand.

Last September, Volvo said it had sold out of its first 1,000 units made, so the increased production target isn't a surprise. Volvo had originally planned to boost annual production to about 5,000 in 2014 – up from about 1,000 this year. A report in Cars UK says Volvo may now try to double that number for next year. The reason for the 10,000 new diesel PHEVs is because Volvo's been "inundated" with orders for the car, which retails for about $80,000. The car can go as far as 32 miles on electric power alone and can scoot from 0 to 60 miles per hour in about six seconds. Plus, hey, diesel plug-in efficiency.
