2019 Corvette ZR1 Convertible

Chevrolet to launch ZR1 convertible

DUBAI, December 3, 2017

Chevrolet has unveiled the 2019 Corvette ZR1 with the global introduction of the ZR1 convertible, the first ZR1 drop-top since the original 1970 model-year ZR1.

On sale next summer alongside the Corvette ZR1 coupe, the ZR1 convertible emphasises Corvette’s iconic proportions and functional sculpture, highlighting the seamless transition between the exterior and interior, said a statement from the company.

Mark Reuss, executive vice president, global product development, purchasing and supply chain, said: “The new Corvette ZR1 convertible is a supercar in all respects.”

“Few others can challenge the ZR1 convertible’s power and speed while offering the exhilaration of top-down motoring,” he said.

The performance and technology introduced on the Corvette ZR1 coupe carry over to the new convertible. The strength of the Corvette’s aluminium chassis means the only structural changes in the convertible are accommodations for the folding top and repositioned seat belt mounts. The power top can be operated remotely or while driving up to 50 kph, it said.

In fact, the curb weight difference between the ZR1 coupe and convertible is less than 27 kg, with most of the difference attributed to the folding top hardware, it added.

“The ZR1 convertible is a no-compromise supercar,” said Corvette executive chief engineer Tadge Juechter.

“Thanks to the strong structure, the suspension tuning between coupe and convertible models is identical, meaning the ZR1 convertible offers the same benchmark performance, including a top speed of over 320 kph,” he added.

The Corvette ZR1’s unique aero package is central to the coupe’s 341 kph top speed. Its standard, stanchion-mounted Low Wing generates road-holding downforce with minimal drag, enabling the benchmark top speed. This was evident during top-speed testing at Germany’s Papenburg proving ground.

An adjustable High Wing is part of the new ZTK Performance Package, which also includes a front splitter with carbon-fiber end caps, Michelin Pilot Sport Cup 2 tyres, and specific chassis and magnetic ride control tuning.

It is designed to help generate faster lap times through maximum grip in the corners, with up to 430 kg of downforce. The top speed is lower with the High Wing but still exceeds 320 kph.

Complementing the ZR1’s aero advantage on the way to 341 kph is the thrust generated by the exclusive LT5 6.2L supercharged engine, which is rated at an SAE-certified 755 horsepower (563 kW) and 715 lb.-ft. of torque (969 Nm).

A seven-speed manual transmission and a ZR1-first paddle-shift eight-speed automatic transmission are offered with it. Preliminary testing has shown 0-60 mph in under 3.0 seconds and the quarter mile in the high 10-second range when the engine is equipped with the eight-speed automatic.

The LT5 features a new, more-efficient, intercooled supercharger system, along with GM’s first dual-fuel-injection system, which employs primary direct injection and supplemental port injection. Compared to the supercharger system on the Corvette Z06’s LT4 engine, the LT5 employs a larger, 2.65-liter supercharger that generates more boost while spinning at a slightly slower speed. That reduces heat to help maintain a lower air intake temperature for optimal performance.

The 2019 Corvette ZR1 coupe and convertible will be on display to the public from December 1 to 10 at the Los Angeles Auto Show, in the US. – TradeArabia News Service
