📖Corvette C7 Targa: the sweet spot of modern open-top Stingray performance

Chevrolet Corvette Targa (C7) (2014-2019)

The Corvette C7 Targa represents arguably the most versatile and appealing iteration of the seventh generation, offering the sculpted, aggressive coupe silhouette alongside an easily unlatched carbon-fibre roof panel that stows in the luggage bay. It provides authentic open-air thrills without the extra weight, complex mechanism, or compromised body styling of a conventional roadster. Practising disciplined Chevrolet Corvette maintenance ensures this charismatic American grand tourer remains totally reliable.

Most European-market models feature the naturally aspirated 6.2-litre LT1 V8 engine developing 460 to 466 bhp, paired with either a seven-speed manual or the eight-speed 8L90 automatic gearbox. Models equipped with the Z51 performance package feature dry-sump engine lubrication, an electronic limited-slip differential (eLSD), and enhanced cooling packs. The 8L90 automatic requires verification that GM's updated synthetic transmission fluid flush has been carried out to eliminate torque converter shudder.

Owner notes

The reassuring points, known weak spots and deadlines you should not let slip.

Reassuring points

Reliability
  • The lightweight carbon-fibre targa roof delivers open-top driving freedom while retaining the rigid spaceframe integrity of the coupe.
  • The naturally aspirated LT1 V8 provides instant throttle response, glorious sound, and proven small-block reliability.
  • With the Z51 package, dry-sump lubrication, and fresh transmission fluid, it delivers outstanding touring and fast road capability.

Chronic weak spots

Keep an eye on
  • LT1 6.2 V8: monitor engine oil level, check Active Fuel Management (AFM) lifters, and inspect direct-injection valves for carbon fouling.
  • 8L90 automatic transmission: check for torque converter shudder under light throttle between 50 and 110 km/h, confirming the revised fluid flush.
  • Removable targa top: inspect front locking handles, rear locating pins, and lubricate weatherstripping to eliminate rattles and leaks.
  • Z51 dry-sump system: verify that oil checks follow GM's hot-check procedure, and inspect auxiliary cooling radiators for debris.
  • Chassis and tyres: inspect Michelin tyre wear across both axles, check alloy wheels for bends, and check front splitter condition.

Critical deadlines

Do not miss
  • Engine oil renewals on dry-sump Z51 models must follow the exact GM warm oil checking procedure to avoid inaccurate oil levels or foaming.
  • The 8L90 automatic transmission must receive GM's updated Mobil 1 synthetic fluid flush immediately if torque converter shudder occurs.
  • Targa roof seals, brake fluid, and engine coolant must be refreshed at strict intervals to maintain cabin quietness and cooling efficiency.
