Audi TT RS Roadster 400HP Review: Performance, Tech, Value

The Audi TT RS Roadster stands as a benchmark in the convertible sports car segment, blending ferocious acceleration, advanced all-wheel-drive technology, and the pure joy of wind-in-your-hair driving. Powered by a distinctive 2.5-liter turbocharged five-cylinder engine producing 400 horsepower, this model catapults from 0-62mph in just 3.9 seconds, making it one of the quickest drop-tops available. Its seven-speed dual-clutch transmission and quattro system ensure every ounce of power translates to the road with unerring precision.

Engine and Powertrain Excellence

At the heart of the TT RS Roadster lies Audi’s renowned 2.5-liter TFSI five-cylinder turbo engine, a masterpiece of engineering that delivers 400hp and 354lb ft of torque from as low as 1,700rpm. This unique powerplant, lighter by 57 pounds compared to its predecessor, provides a broad torque band that propels the car effortlessly through gears, pulling strongly up to the 7,200rpm redline. The soundtrack is equally captivating—a raspy, rally-inspired growl that amplifies with the fabric roof stowed, evoking the glory days of Audi’s Quattro rally cars.

Paired exclusively with a seven-speed S tronic dual-clutch gearbox, shifts are lightning-fast, whether in automatic or manual paddle-shift mode. Launch control enables repeatable sub-4-second sprints, with a top speed electronically limited to 155mph—extendable to 174mph via the optional Performance Pack. The quattro ultra system intelligently distributes torque, sending up to 100% to the rear axle under demand for enhanced agility.

Chassis Dynamics and Handling Prowess

Despite its convertible layout, the TT RS Roadster maintains remarkable structural integrity, with only minimal flex over rough surfaces even at high speeds. Weighing around 199 pounds more than the coupe due to reinforcements, it still feels nimble thanks to front-engine placement and optimized weight distribution. The sport-tuned magnetic ride suspension (standard in higher packs) balances compliance on everyday roads with razor-sharp responses in Dynamic mode.

Steering is precise and quick, offering good directional change without excessive nervousness, though it lacks the raw feedback of some mid-engine rivals. In corners, the car exhibits less understeer than prior generations, rotating eagerly with throttle input, though front-biased dynamics prioritize stability over playful rotation. With ESP off, it reveals more character on track, gripping tenaciously via quattro AWD.

This table highlights the TT RS Roadster’s acceleration edge over key rivals, powered by its superior output and AWD traction.

Design and Aerodynamic Styling

Audi’s aggressive redesign sharpens the TT RS Roadster’s presence with a wider stance, larger air intakes, and a prominent front splitter bearing the quattro badge. Matrix LED headlights and optional carbon fiber accents enhance its muscular profile. The fabric roof deploys in 10 seconds at speeds up to 31mph, folding neatly to preserve trunk space at 8 cubic feet—adequate for weekend luggage but smaller than some competitors.

Wheel options range from 19-inch standards to 20-inch alloys, filled with high-performance Continental tires. The rear features a subtle spoiler and quad exhausts that crackle on overrun, underscoring its RS heritage.

Interior Refinement and Technology

Step inside, and the TT RS Roadster envelops occupants in premium materials: Alcantara and leather bucket seats with RS embroidery, carbon fiber inlays, and a flat-bottomed steering wheel. The Virtual Cockpit digital gauge cluster is a standout, shifting colors in Dynamic mode to signal rev limits and displaying navigation or performance data with customizable views.

Infotainment runs Audi’s MMI system with a 12.3-inch screen, supporting Apple CarPlay and Android Auto. Climate control, Bang & Olufsen audio, and heated seats ensure comfort year-round. As a 2-seater, it prioritizes driver focus over practicality, lacking the coupe’s rear seats.

• Key Interior Features:
• Virtual Cockpit with performance metrics
• B&O premium sound system (optional)
• Sport seats with massage function
• MMI touch response controls
• Ambient lighting in 10 colors

Driving Modes and Everyday Usability

Selectable via a steering wheel dial, modes include Comfort, Auto, Dynamic, and Individual, adjusting throttle, suspension, steering, and exhaust note. Comfort softens the ride for urban commutes, while Dynamic firms everything for track work. Even on 20-inch wheels, the adaptive dampers absorb UK potholes adequately, though firmer setups demand smooth roads.

Fuel economy hovers around 30mpg combined, impressive for its output, with a 13.2-gallon tank offering decent range. It’s surprisingly refined with the roof up, rivaling hardtops in noise isolation.

Pricing, Ownership, and Rivals

Starting at approximately £56,650 in the UK (around $75,000 USD equivalent), prices climb with options like the Dynamic Pack Plus (£2,600) for adaptive suspension and ceramic brakes. Running costs are reasonable for an RS model, with strong residuals due to desirability.

Rivals include the Porsche 718 Boxster S, which offers mid-engine balance but less power; the Mercedes-AMG SLC 43, more GT-oriented; and the BMW Z4 M40i, with manual option charm. The TT RS excels in straight-line speed and all-weather grip.

Performance on Track and Road

On circuits like Jarama, launch control delivers shocking acceleration, and quattro AWD provides confidence-inspiring exits. Road tests praise its composure, though enthusiasts note it favors speed over soul-stirring involvement compared to rear-drivers.

Pros and Cons

• Pros: Explosive power, unique engine sound, AWD security, tech-laden cabin, roof-up refinement.
• Cons: Front-biased handling, limited storage, high price with options, less playful than rivals.
