Dick explained that the company’s newly introduced 3.0L supercharged V6 TFSI engine is actually an “intermediate step” between the former 4.2L V8 and a new range of turbocharged four-cylinder engines. Future versions of the S4 and S5 will be 20% more fuel-efficient but will offer similar performance to the outgoing V8 models.
Smaller engine displacement isn’t the only avenue Audi is investigating as weight reduction is equally important for Audi. Take the new S5, the coupe weighs in at a hefty 3,800 pounds (1,723kg) while the Cabrio tips the scales at 4,300 pounds (1,950kg). According to Dick, Audi’s weight reduction goal for the next-generation of cars is 30%.
