2015 Audi A7 TDI Prestige Sedan 4D The Masterpiece of Sleek Design and Long-Range Diesel EfficiencyThe 2015 Audi A7 TDI Prestige stands as a pinnacle of executive automotive design, effortlessly blending the sweeping, beautiful silhouette of a four-door coupe with the real-world versatility of a spacious fastback rear hatch. While the A7 is universally celebrated for its stunning aesthetics, the highly coveted TDI designation introduces a specialized, ultra-efficient clean-diesel powertrain that transforms this luxury cruiser into a long-range endurance machine. Positioned at the top-tier Prestige trim, this sedan delivers an uncompromising mix of track-inspired handling, cutting-edge digital amenities, and a level of highway efficiency that easily rivals small hybrid vehicles.Under the hood lies a brilliant piece of engineering: a 3.0-liter Turbocharged Clean Diesel V6 engine (TDI), hammering out a smooth 240 horsepower and a massive, locomotive-like 428 lb-ft of torque at just 1,750 RPM. This incredible low-end muscle is routed through a highly refined 8-speed Tiptronic® automatic transmission and Audi's legendary quattro® permanent all-wheel-drive system. Rocketing from 0 to 60 mph in a crisp 5.5 seconds, the TDI provides an immediate, effortless surge of acceleration that makes highway passing and merging completely addictive, all while operating in near-total silence.The driving experience is characterized by a supreme sense of balance, stability, and high-speed composure. Built with extensive aluminum components to keep the chassis lightweight and rigid, the A7 handles corners with flat-out poise while maintaining a plush, isolated ride over road imperfections. The Audi Drive Select system allows you to effortlessly tailor the car's personality across Comfort, Auto, Dynamic, and Individual modesreconfiguring throttle inputs, transmission shift logic, and steering weight to perfectly suit your mood, whether you are commuting down the interstate or carving up a winding road.On the exterior, the 2015 A7 remains an absolute styling triumph, featuring:A low-slung, dramatic roofline with premium, frameless side door glassUpgraded full-LED adaptive headlights with signature daytime running light stripsThe prestigious S-Line exterior package, featuring more aggressive front and rear bumpers and side sillsLarge 20-inch split-spoke alloy wheels that perfectly fill out the muscular fender flaresAn iconic, speed-activated rear spoiler that automatically rises at 80 mph to optimize aerodynamicsInside, the Prestige trim treats passengers to a beautifully crafted, driver-focused cockpit wrapped in old-world materials and intuitive digital tech. It features 12-way power-adjustable heated and ventilated front sport seats draped in premium perforated Milano leather.

Standard premium finishes include ambient interior lighting, genuine fine wood inlays, and a magnificent 14-speaker Bose® Centerpoint® Surround Sound System.Practicality is where the A7 fastback layout completely dominates traditional executive sedans. While it maintains a clean, coupe-like profile from the side, the entire rear glass lifts up as a massive power tailgate. This wide opening reveals a generous 24.5 cubic feet of trunk space, which easily expands to accommodate larger cargo, commercial gear, or professional luggage sets when the 60/40 split-folding rear seats are stowed flat.
