Greatly revised for 2015, the Audi TT coupe and roadster has undergone many steps to modernize itself for improved performance, as well as luxury. The exterior alterations to the 2015 Audi TT, compared to its predecessor, are largely subtle with exception to the front. The 2015 Audi TT adapts a meaner-looking pair of standard HID headlights and a new hexagonal-shaped grille. Increased use of aluminum on the 2015 Audi TT also allows the vehicle to be lighter than the previous year’s model. While the weight of the 2015 Audi TT decreased, engine power has increased. The 2.0 TFSI engine generates 230 horsepower for the 2015 Audi TT’s quattro all-wheel drive system. A six-speed S Tronic dual-clutch transmission provides management of the power for the livelier 2015 Audi TT. The modern interior of the 2015 Audi TT features a 12.3-inch multi-function instrument display. Called the Audi virtual cockpit, the 12.3-inch display provides the driver with a preferential view of driving as well as convenience controls inside the vehicle. MMI radio, air conditioning, cruise control and a full array of airbags are standard on the 2015 Audi TT sports car. The 2015 Audi TT will also provide available 4G LTE connectivity.
