Next-gen Audi TT to become a four-door coupe?

Iconic coupe might get two more doors to combat falling sales, rising investment.

Four years ago, Audi showed the TT Sportback concept at the Paris Motor Show, the third TT-based fancy revealed in 2014 after the two-door Allroad Shooting Brake and four-door TT Offroad concepts. At the time, former Audi R&D head Ulrich Hackenberg suggested “a possible TT family.” A few years of pandemonium delayed whatever plans Audi had at the time, but it appears the Ingolstadt carmaker will move ahead with a production version of the TT Sportback concept. Both Auto Express and Auto Bild report that the next generation will become a four-door coupe, replacing the two-door coupe and roadster on sale now.

The two publications say Audi bosses have already approved the four-door’s final design. We can’t know the final dimensions of the production four-door, but the Mars Red TT Sportback concept was a touch more than 11 inches longer and two inches wider than the current third-generation production TT. The concept’s roof sat an inch lower, and the wheelbase stretched almost five inches longer than the span on the TT.

If there’s anything a sporty buyer would want from the concept, it’s the engine. The 2.0-liter TSFI turbocharged four-cylinder EA888 received heavy mods, putting out 400 horsepower at 6,400 rpm
and 331 pound-feet of torque, good for a 0-62 mph dash in 3.9 seconds. The same engine in the TTS produces 292 hp and 280 lb-ft, taking 4.6 seconds to get to 60 mph. You have to climb up to the 2.5-liter five-cylinder in the TT RS to reach the 400-hp mark.

That flavor of madness isn’t likely, but the engine range is expected to expand. On top of standard gasoline engines with mild hybrid help, there could be a plug-in hybrid, “a new generation of electrified diesel engines,” and a fully electric version.

When the TT Sportback appears “in showrooms in less than two years” on a version of the TT’s MQB platform, it will compete with the anticipated BMW 2 Series Gran Coupe and Mercedes-Benz CLA.
