The Car Connection's Take
TCC Rating
9.0
8.2
TCC’s Bottom Line
The Audi A8 gains standard LED headlamps, a more powerful twin-turbo V-8, and a more efficient diesel engine for 2015. The Regal GS is the best driver's car in the Buick lineup, and it makes for an interesting alternative for cars like the Volvo S60.
