At the center of the ZR1 is a 5.5L twin-turbocharged DOHC flat-plane crank V8 engine referred to as the LT7. This engine delivers 1,064 horsepower at 7,000 rpm and 828 lb-ft of torque at 6,000 rpm, marking it as probably the most potent manufacturing unit Corvette engine ever. The ZR1 achieves a GM-estimated prime pace of over 215 mph and completes the quarter mile in beneath 10 seconds, in line with GM estimates. The automobile’s carbon fibre aero package deal generates over 1,200 kilos of downforce at prime pace, contributing to its unbelievable monitor efficiency. Additionally, the ZR1 brings again a legendary Corvette design cue: the cut up rear window.
“The crew that revolutionized Corvette with a mid-engine structure took on one other problem: take ZR1 to the following stage,” mentioned Scott Bell, vp of Chevrolet. “Corvette ZR1 is about pushing the envelope with uncooked energy and cutting-edge innovation. From Stingray to Z06, E-Ray, and now ZR1, the Corvette household continues to raise with every new iteration — and problem one of the best on the planet.”
Engine growth for the ZR1 centered on maximizing energy and functionality. The LT7 engine builds on the structure of the Z06’s LT6, including twin turbochargers for the primary time in a manufacturing unit Corvette. Engineers optimized almost each system for boosted efficiency, leading to a novel 5.5L twin-turbo DOHC flat-plane crank engine that mixes engineering precision with track-tested energy.
The inside of the ZR1 is tailor-made for efficiency and luxurious, with ZR1-specific badging, distinctive sew patterns, and a lift gauge that highlights the primary manufacturing unit turbocharged Corvette. The cockpit additionally gives in depth customization choices, together with a brand new Habanero inside, blue stitching, and a number of racing stripe and brake calliper color decisions.
Design-wise, the ZR1 reintroduces the split-window fashion, a nod to the C2-generation Corvette, which boosts each aesthetics and performance. The cut up window’s carbon fibre backbone improves engine cooling whereas serving as a hanging design factor. The automobile’s light-weight carbon fibre roof and distinctive aluminium wheels, obtainable in 4 finishes, cut back weight and decrease the centre of gravity.
Key options of the LT7 engine embody redesigned head castings with bigger combustion chambers, an consumption system tuned particularly for turbochargers, and electronically managed wastegates. The engine additionally advantages from superior cooling techniques, secondary port gasoline injection, and upgraded crank prepare parts to deal with the large output. The engine’s rev-happy character stays intact whereas delivering over 1,000 horsepower. Supporting this energy is a strengthened eight-speed dual-clutch transmission, with strengthened gears and upgraded enter shafts. The transmission’s oil administration and management valves have been optimized to deal with the elevated calls for of the LT7 engine.
Aerodynamics play a vital position within the ZR1’s efficiency, with carbon fibre parts and a meticulously designed flow-through hood that will increase entrance downforce whereas managing intercooler temperatures. The facet profile ducts and contemporary air consumption techniques additionally contribute to cooling key parts, whereas the obtainable ZTK efficiency package deal provides aggressive aero components like a high-downforce rear wing and entrance dive planes for monitor use.
The ZR1’s chassis is engineered for pace with a sleeker physique that features a commonplace carbon-fibre entrance splitter, rocker mouldings, and Michelin Pilot Sport 4S tyres. The automobile’s suspension contains Magnetic Ride dampers and is designed to stability monitor efficiency with on-road consolation. For these in search of most monitor functionality, the ZTK package deal gives stiffer suspension, Michelin Pilot Sport Cup 2 R tyres, and carbon fibre underbody strakes.
Braking efficiency is enhanced by a carbon ceramic brake system that includes 15.7-inch entrance rotors — the most important ever on a Corvette — and modern manufacturing strategies that enhance sturdiness whereas lowering temperatures. The ZR1’s stopping energy is unmatched, accelerating from 80 to 200 mph and again to 80 mph 22% faster than the earlier era C7 ZR1. The ZR1 is ready to enter manufacturing in 2025 at General Motors’ Bowling Green Assembly Plant in Kentucky, becoming a member of the Corvette Stingray, Z06, and E-Ray fashions.
