A quick look at 28 new luxury vehicles to watch out for in 2010

2010 Audi A3
An all-new Audi A3 is coming in a couple of years, but we wanted to highlight an important change to the lineup for 2010. No, it's not the subtly restyled nose, nor the LED-enhanced headlights, nor the minor revisions to the rear end. Instead, it's the addition of an available diesel engine in the new TDI model, which in a lot of ways puts the A3 in a class by itself. Audi's banking on diesel as the green technology of tomorrow, and this is a good one: Official fuel economy numbers aren't in yet, but the A3 TDI got more than 50 mpg during a cross-country publicity stunt earlier this year.
