2023 Chevrolet Corvette Z06 spied again – will it finally topple the Porsche 911 GT3?
Chevrolet isn’t holding back with its incoming mid-engined Corvette Z06, but will it make it across the pond officially?
New images of the upcoming Chevrolet Corvette Z06 have surfaced, flaunting its aggressive aero kit, wider body and what’s likely to be a new flat-plane crank V8 under the composite engine cover. The base C8-generation Corvette Stingray was launched last year, making headlines with its all-new chassis and mid-engined layout, turning firmly from a composite-clad American sports car to something rather more sophisticated. Yet the standard C8 was never the real cause for this fundamental change with ‘just’ 495bhp, rather Chevrolet’s ambition to truly rival European supercars with the incoming Z06, which now firmly has cars like the 911 GT3, Lamborghini Huracan STO and McLaren 765LT in its crosshairs.
In these new images, the Z06 prototypes have shed most of their shape-shifting padding, exposing the wider bodywork and aggressive new aero package. All major exterior panels, save for the roof, bonnet and door skins, look to be bespoke from the Stingray, with a substantially more open front bumper that looks to be fitted with no less than three massive radiators and two channelled cooling ducts. The side intakes are also bigger, and around the back, the exhausts have now moved to a central position within the rear valance, leaving space on either side for more aero trickery.
Another major difference to the C8 Stingray is the dramatic increase in wheel offset – that is the point at which the wheel is bolted to the wheel hub in relation to the body. In standard Stingray models, the wide axle, but narrow offset makes it look boxy and awkward over both axles. It’s possible this has been a conscious decision to fit both Stingray and Z06 models with the same rear axle design to save on the development costs, with the Z06 theoretically just needing to be fitted with wider wheels with some proper offset and those swollen wheel arches. Looking at the five-spoke wheel design, we’d say this had definitely been addressed.
Chevrolet has also released an official sound clip of the new Z06 ahead of its autumn reveal. The teaser as much as confirms the use of a high-revving flat-plane crank V8 – once a bastion of highly-strung engines found in Ferraris and McLarens. As with the Stingray, the Z06 will only be available with a dual-clutch transmission, but at the sort of performance levels expected a six-speed manual transmission would likely have had a low take-up, as was the case with the previous-generation Z06.
Given the Z06’s connection to Chevrolet’s sports car racing activities, we suspect this new V8 to be connected to the unit being developed for the Corvette C8-R racer, one that differs aurally from the off-beat grumble of Chevrolet’s traditional small blocks with a high-pitched, almost European-sounding shriek typical of a flat-plane crank.
Final engine outputs are still under wraps, but it’s likely that the C8 Z06 will produce more power than the supercharged 6.2-litre LT4 from its predecessor – in its final form, that car made 641bhp and 650lb ft of torque for a 3sec 0-60mph time and 185mph top speed.
Due to be revealed in autumn 2021 as an American 2023 model, the Z06 could finally become the European supercar killer it’s always threatened to be. With right-hand-drive production plausible, it’ll likely be Europe’s emissions regulations that will govern whether the UK and Europe will be able to experience Chevrolet’s more potent Corvette models with the steering wheel on the correct side.
