We've already seen spy shots of what is likely to be the 2018 Chevrolet Corvette ZR1 in coupe form. Now come shots of a future ZR1 Convertible.

Photographer David Wesel captured both the coupe and the convertible testing in Marrrieta, Ohio, and the those photos are posted on CorvetteBlogger. A couple are shown here.

In the shots, the convertible features a prominent rear wing, but this one is shorter than the one we've seen in previous coupe spy shots. The convertible also has the Ferrari [NYSE:RACE]-style pentagram wheels we've seen before.

According to Wesel, the car was spotted with six other Corvettes, as well as a Jaguar F-Type and a Dodge Challenger SRT Hellcat. Corvette product manager Harlan Charles was reportedly with the group and driving a Corvette Grand Sport at the time.

It's not really a surprise that Chevrolet would release a convertible ZR1. High performance cars like this used to be limited to coupes. For instance, the C6 ZR1 was only offered as a coupe. However, Chevrolet is offering the current Grand Sport and Z06 as convertibles and those are rather accomplished track cars.

The last ZR1 arrived for the 2009 model year. With a supercharged 6.2-liter V-8 making 638 horsepower and 604 pound-feet of torque under the hood, it delivered rip-snortin' performance. Those figures are already exceeded by the C7 Z06, which has 650 hp, so expect the next ZR1 to maybe top 700 horses.

General Motors Company [NYSE:GM] is known to be working on a new LT5 V-8, though this will likely be reserved for the C8. Instead, look for an uprated version of the C7 Z06’s LT4 V-8.

We expect the C7 ZR1 to be unveiled at next January’s 2017 Detroit auto show and pricing to exceed $100,000. These may be the last of the high-performance front-engine Corvettes. If so, they will certainly be collectible.
