In 2008, Audi revealed one of the wildest concepts ever built — the R8 V12 TDI 🚗🔥 A true one-of-one masterpiece powered by a 6.0L twin-turbo diesel V12, pushing 493 hp and an insane 738 lb-ft of torque. Paired with a 6-speed manual and quattro AWD, it launched 0–60 mph in just 4.2 seconds and could exceed 186 mph — all on diesel. Audi never put it into production, making this brutal supercar one of the rarest and most ambitious concepts in automotive history. #technology #cars #AUDI🚘
