reference Awards was placed in the 2004 annual list of Ward's 10 Best Engines 4.0 TFSI This engine is part of Audi's modular 90° V6/V8 engine family. It shares its bore and stroke, 90° V-angle, and 90mm cylinder spacing with the Audi V6. The earlier V6 engines (EA837) used an Eaton TVS Supercharger instead of turbocharger(s). In 2016, Audi and Porsche released a new turbocharged V6 engine they dubbed EA839. These 2.9L (biturbo) & 3.0L (single turbo) V6 engines share the 4.0T TFSI V8's “hot vee” design, meaning the turbo(s) are placed in the Vee of the engine (between each bank of cylinders) instead of on the outside of each cylinder bank. This allows the turbocharger(s) to produce boost pressure more quickly as the path the exhaust gases travel is much reduced. It also aids in getting the engine's emissions hardware up to temperature more quickly. As with the V6, the V8 is used in various Audi and Porsche models, but the V8 also finds use in Bentley and Lamborghini vehicles. engine displacement & engine configuration 90° V8 engine; cylinder spacing; bore x stroke: , stroke ratio: 0.95:1 – undersquare/long-stroke, 499.1 cc per cylinder, compression ratio: 10.5:1 fuel system; Fuel Stratified Injection (FSI) Central-Overhead Injectors exhaust system two twin-scroll turbo chargers and twin air- and water-cooled intercoolers DIN-rated motive power & torque outputs, ID codes, applications at 5,500 rpm; from 1,400 rpm to 5,400 rpm— CEUC: Audi S6 C7, S7, CEUA: A8 D4 at 5,800 rpm; from 1,400 rpm to 5,300 rpm— CTGA: A8 D4, A8 D5 at 6,200 rpm; from 1,700 rpm to 5,500 rpm— DDTA: Audi S8 D4 (overboost to 750 Nm), CWUC: Audi RS7 performance(C7), Audi RS6 performance (C7) at 5,700 rpm; from 1,750 rpm to 5,500 rpm— CRDB, CWUB: Audi RS6 C7 and RS7 C7 at 5,500 rpm; from 1,800 rpm to 4,500 rpm— CXYA: A8 D5, Porsche Panamera GTS at 5,500 rpm; from 1,800 rpm to 4,500 rpm in Porsche Panamera GTS (Facelifted) at 6,000 rpm; from 1,700 rpm to 5,400 rpm in Bentley Continental GT V8 and Flying Spur V8 at 6,000 rpm; at 1,750 rpm to 5,500 rpm in Bentley Continental GT V8 S at 5,500 rpm; from 2,000 rpm to 4,000 rpm in Audi SQ7 and SQ8 from 5,750 rpm to 6,000 rpm; from 1,960 rpm to 4,500 rpm in Porsche Panamera Turbo, Turbo S E-Hybrid, Bentley Continental GT V8 (2019–) and
