How to spot an Audi R16: Part 6: 2015 Audi R8 LMS GTD Version

The Audi R8 LMS which competes in the GT Daytona class (GTD) of the TUDOR United SportsCar Championship has its roots in the Audi R8 GRAND-AM, which debuted in the Rolex GRAND-AM GT class at the beginning of 2012. The Audi R8 GRAND-AM was again used in 2013, before being updated for its use in the GTD class of the newly formed TUDOR United SportsCar Championship, a merger of the Rolex GRAND-AM Series and the American Le Mans Series (ALMS). Heading into the new TUSC the car was known as the GTD version of the Audi R8 LMS.

We have included a comparison of the 2014 and 2015 Audi R8 LMS GTD versions. The Audi R8 LMS has remained mostly unchanged, with differences for 2015 mainly being focused on the addition of a larger rear-wing, following BoP changes for the 2015 season.

1. The new rear wing is the only major change on the 2015 Audi R8 LMS in the GTD class. One of the deficiencies of the previous GTD and Grand-AM Audi R8 LMS versions was the lack of downforce, especially at the rear under heavy braking. The aggressive R8 LMS ultra rear diffuser was added in 2014 to aid the downforce levels at the rear of the car and now for 2015 a larger rear wing has also been permitted. The Audi R8 LMS in the GTD class will now be allowed to use the Crawford 72-inch spec rear wing, an increase over the previous 60-inch version.

2. Along with the addition of the Crawford 72-inch spec rear wing, the Audi R8 LMS will also be allowed to use double front dive planes, two on each side of the car. This is to balance the front and rear downforce due to the increased downforce at the rear. The larger double dive planes now replace the old smaller single dive planes.
