2. Audi 4.0 Twin-Turbo TFSI DOHC
Although Audi has perfected five-cylinder turbocharged engines and high-revving V10 featured in its R8 supercar and Lamborghini Gallardo/Huracan, the latest gem from Ingolstadt is a fantastic twin-turbo V8 with 4.0-liters of displacement and the latest in direct injection technology and engine management.
The result is fantastic – 591 HP and 590 lb-ft of torque. This V8 is destined to debut in the brand-new 2020 Audi RS6 Avant, the fastest station wagon currently on sale. Also, it will be installed in other Audi models in the future.
