Look at Audi's 2015 model lineup and one thing becomes clear: the company's engineers and designers certainly haven't been enjoying a lot of leisure time. While many of the automaker's models may appear to be direct carryovers from 2014, the truth is most models--such as the A4/S4, A5/S5/RS 5, A6/S6, A7/S7/RS 7, and TT/TTS--return with changes ranging from added standard features to new paint colors and option packages. The A8 and S8 go a step further with updated front and rear styling, and the R8 is tweaked with an Alcantara headliner and Laser Red brake calipers. Audi's Q5 and Q7 crossovers and Allroad wagon have been updated as well, and are now joined by the all-new, 4-cylinder-powered Q3. Also making its debut is the 2015 A3, a smaller alternative to the A4, one that's available in sedan and convertible body styles.
