The C7 A6 features more aggressive styling as compared to the C6 as well as an upgrade to the 3.0T engine. The 3.0T has proven itself to be reliable, even when substantially upgraded. APR's stage 1 tune brings the power output to 410 HP / 364 TQ and jumping up to an APR Ultracharged tune bumps the output to an incredible 460 HP / 429 TQ on pump gas!
