2013 Porsche Cayenne DieselEnlarge Photo
If you're in the market for a luxury or sports car, regular diesels and hybrids like the Volkswagen Jetta or Toyota Prius are unlikely to be on your list.
Porsches might, however--and those still wanting to save a few dimes on gas or pump out just a little less emissions into the atmosphere may be interested in the Cayenne Diesel and Hybrid SUVs, or the Panamera Hybrid luxury sedan.
2013 pricing has been announced for each model, and it's the 2013 Porsche Cayenne Diesel that'll get you better gas mileage for the least money.
Starting at $55,750 plus $950 destination charge, the Cayenne Diesel's 3.0-liter, six-cylinder engine will get you 23 miles to every gallon of diesel. That stretches to a respectable 29 mpg at highway speeds.
Better still is the Panamera S Hybrid, though you pay for the privilege. The luxury sedan manages 25 mpg combined and 30 on the highway, with prices starting at $96,150, plus $975 destination.
In the middle, the Cayenne S Hybrid starts from $69,850 plus $950 destination fee, and official EPA combined economy reaches 21 mpg. You'll likely be buying this one for the badge alone, since there are certainly more efficient hybrid SUVs out there--the 2013 Lexus RX 450h gets a 29 mpg combined rating, in all-wheel drive trim. The plug-in Cayenne can't come soon enough...
Porche's hybrid line-up doesn't stop at SUVs and luxury sedans, however.
Also present on the price list is the 2014 Porsche 918 Spyder. The plug-in hybrid supercar will be the world's most expensive hybrid when it goes on sale, with an eye-watering price tag of $845,000.
Hugely powerful and hugely fast, the 918 is rumored to deliver economy of up to 78 mpg--though admittedly it isn't the most accessible of green vehicles...
Still, for those with even more green to spend, there's always the Weissach Package--less weight and even more performance. You'd better sit down for the price--$929,000.
After that, $56,000 of Cayenne sounds quite reasonable...
