Audi S8 2012-2018 Specifications

The 2012-2018 Audi S8 features a 4.0L TFSI twin-turbocharged V8 engine producing 520 horsepower and 481 lb-ft of torque. This engine incorporates cylinder deactivation technology, allowing it to run on four cylinders during light loads for improved fuel efficiency. The engine was developed in collaboration with Bentley and features twin-scroll turbochargers located within the 'V' of the engine for minimal turbo lag.

The S8 comes exclusively with an 8-speed Tiptronic automatic transmission and Quattro all-wheel drive. The transmission features sport-tuned shift mapping and paddle shifters. The Quattro system has a standard 40:60 front-to-rear torque split and can dynamically adjust power distribution based on driving conditions.

Besides the powerful engine, the S8 features adaptive air suspension, dynamic steering, and sport differential. The car can accelerate from 0-60 mph in 3.9 seconds despite weighing over 4,600 pounds. Carbon ceramic brakes are optional for enhanced stopping power.

The S8 achieves EPA ratings of 15 mpg city and 24 mpg highway. While not exceptional, these figures are impressive considering the vehicle's performance capabilities and size. The cylinder deactivation system helps improve efficiency during highway cruising.

Audi recommends oil changes every 10,000 miles or 12 months, brake fluid replacement every 2 years, and spark plug replacement every 40,000 miles. The air suspension system should be inspected regularly, and the transmission fluid should be changed every 80,000 miles.

Standard features include MMI Navigation plus, Audi pre sense plus, adaptive cruise control, and a 19-speaker Bang & Olufsen sound system. The car also features LED headlights, a head-up display, and Audi's advanced parking system with 360-degree cameras.

The S8 offers generous interior space with 41.4 inches of front legroom and 38.7 inches of rear legroom. The trunk provides 14.2 cubic feet of cargo space. The extended wheelbase version (not available in all markets) offers additional rear legroom.

The S8 features unique exterior styling with aluminum-look mirrors, quad exhaust tips, and S-specific wheels. It also includes sport seats with diamond quilting, carbon fiber trim, and a sport-tuned suspension. The S8 offers significantly more power and performance-oriented handling compared to the standard A8.
