2014 Audi A8 L TDI
The Story: At last year's L.A. Auto Show, Audi took the opportunity to unveil debuts for four clean diesel-engine (TDI) options in their line of high-end sedans -- the A6, A7, A8 and Q5. Well, they're here. The A8 (above) is the flagship of the Audi brand and has a 3.0-liter V-6 turbodiesel engine that exerts 240 hp and 406 lb-ft of torque on the outside world -- while consuming less fuel and reducing carbon emissions. If there's any knock, it's the $83,395 base price. Still with me? Look to the lower-end models for more eco-friendly models ("eco" meaning economics in this case).
