TTS Vs A110 Vs 718 Cayman: 3-Way Road And Track Test

In the competitive world of mid-engined sports cars, the Audi TTS, Alpine A110 Pure, and Porsche 718 Cayman stand out for their blend of performance, agility, and style. This comparison dives into their engineering, on-road capabilities, and real-world usability to crown a winner for enthusiasts seeking pure driving joy.

Powertrains and Technical Specs

Each car employs a turbocharged four-cylinder engine, but their configurations differ significantly. The Alpine A110 Pure uses a 1.8-litre inline-four producing 248bhp at 6,000rpm and 320Nm from 2,000rpm, paired with a seven-speed dual-clutch transmission driving the rear wheels. Its standout feature is the ultra-lightweight aluminium chassis, tipping the scales at just 1,098kg.

The Porsche 718 Cayman opts for a 2.0-litre flat-four turbo engine delivering 296bhp at 6,500rpm and a robust 380Nm from 2,150rpm. It comes with a six-speed manual gearbox in this test, also rear-wheel drive, but weighs more at 1,335kg. This setup emphasizes torque delivery for effortless acceleration.

Audi’s TTS features a 1,984cc inline-four turbocharged unit with 302bhp at 5,400rpm and 400Nm from 2,000rpm, linked to a seven-speed dual-clutch and quattro all-wheel drive. At 1,405kg, it’s the heaviest, but the extra grip compensates in straight-line speed.

Acceleration and Speed Tests

Straight-line performance reveals key strengths. The Audi TTS leads with a 0-60mph time of 4.1 seconds, thanks to its high torque and all-wheel drive launch. The Alpine A110 Pure follows closely at 4.7 seconds, benefiting from its low mass, while the Porsche 718 Cayman records 5.6 seconds, prioritizing chassis balance over outright sprint.

In-gear acceleration highlights the lightweight advantage of the A110. From 30-70mph, it posts 3.8 seconds, edging out the TTS at 3.6 seconds and Cayman at 3.1 seconds. Top-gear pulls from 50-70mph see the A110 quickest at an impressive 5.7 seconds in similar tests, outpacing the Porsche (9.3s) and Audi (8.0s).

Further breakdowns show nuance: in third gear 30-50mph, Audi manages 2.2 seconds, Alpine 2.0 seconds, and Porsche 2.8 seconds. The Cayman’s torque shines in fifth gear 50-70mph at 3.0 seconds, beating rivals.

Handling and Driving Dynamics

On twisty roads, the Porsche 718 Cayman excels with its mid-engine layout and precise manual shifter, offering exceptional composure and feedback. Testers note its ability to sweep through corners effortlessly, making it the benchmark for dynamic prowess.

The Alpine A110 impresses with lively chassis feedback, feeling more engaging than the Audi despite less ultimate grip. Its low weight allows playful handling, keeping pace on winding routes without feeling outclassed.

The Audi TTS provides secure, all-weather grip via quattro, but its heavier steering and numb feel lag behind in pure driver involvement. It’s fast and planted, yet less communicative.

• Porsche 718 Cayman: Supreme balance, agile through bends, rewarding manual.
• Alpine A110: Featherlight, feedback-rich, fun alternative.
• Audi TTS: Grippy AWD, but less engaging.
