2012 Porsche 911 Carrera S Cabriolet

2012 Porsche 911 Carrera S Cabriolet

Porsche has yet to unveil the all-wheel-drive Carrera 4 and 4S coupe and convertible versions of the latest 911, but fuel-economy ratings for the new models have surfaced online. As with the two-wheel-drive 911 Carrera and Carrera S, the new 911 4 and 4S are more efficient than were the outgoing cars. The appearance of the EPA ratings also indicates that the all-wheel-drive cars will be the next 911 variants to go on sale.

The 2013 Carrera 4 and 4S have different engines, just like their rear-drive counterparts; the 4 is powered by the same 3.4-liter flat-six as the Carrera, and the 4S shares its more-powerful 3.8-liter engine with the Carrera S. Given that the new 3.4-liter engine in the non-S models is smaller than last year’s base 3.6-liter six and the S cars’ 3.8-liter displacement is unchanged, you’d expect a bigger fuel-economy bump in the base cars. And you’d be correct.

The 2013 911 Carrera 4 coupe equipped with the seven-speed dual-clutch automatic now gets 20 mpg in the city and 28 on the highway, improvements of 2 mpg on each cycle. Carrera 4 coupes with the manual see their efficiency jump by 1 mpg to 19 in the city and by 3 mpg on the highway to 27. Highway mileage for the 2013 Carrera 4 cabriolet with the automatic improves by 1 mpg, to 27 mpg, while city economy improves by 2 mpg to 20. There is a minor 1-mpg improvement on both cycles for the manual cabriolet, to 19/26.

As for the 2013 Carrera 4S coupe and cabriolet, the 4S coupe with the automatic sees its city economy rise by 1 mpg to 19—its highway figure of 26 mpg is unchanged. The opposite is true for the 4S manual, which gets the same 18 mpg in the city as last year, but nets one additional mpg on the highway for a total of 26. Strangely, the 2013 4S cabriolet with the automatic is now rated for 19/26 mpg—that’s 1 mpg more for the city cycle than 2012, but a reduction of 1 mpg on the highway; the stick-shifted droptop 4S’s EPA figures rise by 1 mpg on both cycles to 18/26.

There’s been no official word on when we can expect to see the 911 Carrera 4 and 4S models, but we’d wager that it’s sometime soon.
