The 2025 Chevrolet Corvette ZR1 made its world debut tonight, and boy does it ship! The King of the Hill returns with essentially the most highly effective V8 ever produced in America from an auto producer, mind-bending specs and iconic design to problem the world’s finest supercars in each coupe and convertible variants.
Corvette ZR1 contains a 5.5L, twin-turbocharged DOHC flat-plane crank V8 engine (LT7).
The LT7 engine produces 1,064 horsepower at 7,000 rpm and 828 lb-ft of torque at 6,000 rpm — essentially the most energy ever from a manufacturing facility Corvette and essentially the most highly effective V8 ever produced in America from an auto producer.
Corvette ZR1 boasts a GM-estimated high velocity of over 215 mph on the racetrack and can rip by way of the quarter mile with a GM-estimated sub-10-second time.
Purposeful carbon fiber aero package deal creates over 1,200 kilos of downforce at high velocity.
ZR1 revives one of the crucial iconic kinds in Corvette historical past: the cut up rear window.
“The workforce that revolutionized Corvette with a mid-engine structure took on one other problem: take ZR1 to the subsequent degree,” mentioned Scott Bell, vp, 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.”
Pushing the boundaries of Engine Improvement
ZR1’s 5.5L LT7 twin-turbocharged DOHC V8 engine begins with the identical structure as Z06’s LT6, essentially the most highly effective naturally aspirated manufacturing V8 engine ever, and takes it to the subsequent degree with twin turbochargers — the primary time ever for a manufacturing facility Corvette.
Dubbed the “Gemini V8” structure, the LT6 program was solely the start as engineers dual-pathed a purpose: to create large energy, functionality and character from naturally aspirated and turbocharged flat airplane crankshaft twin engines. With these objectives in thoughts, engineers didn’t create an LT6 with turbochargers, however as a substitute modified and optimized just about each system for a boosted software.
Corvette ZR1’s 5.5L, twin-turbo DOHC flat-plane crank LT7 engine is the results of engineering prowess and pushing the boundaries of what the engine structure can do. Considerate planning produced one of the best efficiency from pressured induction, married with the 5.5L flat-plane engine structure.
Distinctive to the 5.5L LT7 twin-turbo V8 are:
Head castings with distinctive ports and a bigger combustion chamber
Valve prepare timing and elevate profile optimized for pressured induction with larger exhaust temp enabling exhaust valves
Fully new consumption system tuned for twin turbochargers
CNC machined combustion chamber, exhaust and consumption ports particular to the LT7
Twin, ported shroud, ball bearing, mono-scroll (76 mm) turbochargers built-in with the exhaust manifold to scale back the quantity and distance from the exhaust valve to the turbine wheel for fast response with digital wastegates
Clever anti-lag engine calibration strategies particularly for ZR1 that adapt and react to driving fashion
The LT7 engine additionally builds upon this engine structure with:
Added block and head machining to help turbo cooling and oiling
Counterweight modifications to account for a novel piston, and distinctive connecting rod for the crank prepare
A secondary port gas injection system added to ship the wanted extra gas to help the engine’s large output
To help the dramatic improve in energy from the LT7 engine, engineers made quite a few modifications to the Corvette ZR1’s eight-speed dual-clutch transmission, together with:
Interior and outer enter shaft upgrades
Elevated gear capability with power elevated through shot peening for all gears
Remaining drive refinements
Oil administration to help elevated automobile longitudinal and lateral functionality
Elevated management valves to accommodate the upper required clutch clamp load for LT7
The LT7 engine is purpose-built to perform its four-figure horsepower mission with no compromises in componentry and maintains the rev-happy character that’s the coronary heart of the Gemini V8 engine household. Will probably be hand-assembled by the grasp engine builders on the Efficiency Construct Heart, a part of the Bowling Inexperienced Meeting Plant in Kentucky.
Enabling velocity with ease
Purposeful aerodynamics present essentially the most downforce ever from a Corvette with over 1,200 kilos at high velocity.
The Corvette ZR1 presents velocity on faucet like no Corvette earlier than it. Two distinct setups, full with Magnetic Journey dampers, accomplish this. The usual Corvette ZR1 chassis arrives with a sleeker physique with decrease drag and a small spoiler with customer-adjustable quick and tall wickers. It additionally consists of a normal carbon-fiber entrance splitter, rocker moldings, aspect consumption with built-in brake cooling, and entrance underwing with stall gurney deflectors.
Michelin Pilot Sport 4S tires wrap 20-inch entrance, and 21-inch rear wheels. The usual chassis blends one of the best of on-road consolation and observe functionality with this setup.
Corvette ZR1 dispatches the world’s hardest tracks with ease, not solely with the facility from the 5.5L LT7 engine, but additionally on account of extra, particular aerodynamic and cooling modifications discovered all through the automobile. These embrace:
Movement-through hood: Air enters the entrance grille, flows by way of the intercooler warmth exchanger and exits the hood to extend entrance downforce and funky charged air temperatures.
Carbon fiber aspect profile air ducts: Clear, cool air is funneled by way of ducts, that are cleanly built-in into the signature wishbone bezel behind the cabin doorways to chill the rear brakes by way of an intricately designed system that doesn’t influence rear wheel journey.
Distinctive contemporary air consumption ducts: Carbon fiber inlets situated on high of the coupe rear hatch ingest air to chill the turbo compressor inlet air temperatures.
Corvette ZR1’s non-compulsory ZTK efficiency package deal unlocks a real observe weapon. Notably, the ZTK package deal provides an aggressive, high-downforce rear wing, entrance dive planes, and a tall hood Gurney lip – all constructed from woven carbon fiber. Beneath, underbody strakes exchange the usual entrance underwing stall Gurney to extend entrance downforce. The suspension tuning included within the ZTK package deal incorporates stiffer springs and provides Michelin Pilot Sport Cup 2 R tires. Amid testing and growth, the ZR1 tackled some the world’s most demanding racetracks, together with the Nürburgring, Highway Atlanta, and Virginia Worldwide Raceway.
“We went into the ZR1 program with lofty objectives, however even our first growth assessments on-track confirmed the groups have been already exceeding them,” mentioned Tadge Juechter, government chief engineer, Corvette. “As we labored to develop this automobile, we continued to leap previous expectations, and we knew we had a particular Corvette on our palms.”
Controlling Corvette ZR1’s excessive efficiency is a brand new brake system. The brake package deal makes use of a revolutionary carbon ceramic rotor manufacturing know-how to yield elevated sturdiness and decreased brake element temperatures. Entrance rotors measure 15.7 inches in diameter and rear rotors 15.4 inches in diameter (the entrance rotors are the biggest ever outfitted on Corvette). In simply 24.5 seconds, the 2025 Corvette ZR1 goes from 80-200 mph and again to 80 mph — 22% faster than the C7 Corvette ZR1, and 53% faster than the C6 Corvette ZR1.
Designed for the cut up window’s return
For ZR1, perform and kind rapidly took maintain to create an on the spot icon — an icon worthy of the historic cut up window’s return.
“We didn’t strategy this choice flippantly, we all know this can be a beloved factor from Corvette’s historical past,” mentioned Phil Zak, government design director, Chevrolet. “Not solely does this factor present perform, however we have been capable of combine passionate design into the shape and do it in a manner that paid homage to Corvette’s historical past. ZR1 felt like the best time to carry the split-window again.”
Final seen on the C2-generation Corvette, and quietly previewed on the Corvette Z06 GT3.R race automobile, the split-window fashion capitalizes on the design assertion that’s Corvette ZR1. Whereas serving as a press release piece, this carbon fiber “backbone” between the 2 rear home windows, accessible in uncovered weave or physique shade, supplies elevated warmth extraction from the engine compartment, working in parallel with quite a few different cooling components all through ZR1.
The groups labored to raise the placing design first revealed with the eighth-generation Corvette Stingray and intensify traces that evoke the automobile’s sense of movement — however the design’s perform additionally helps it carry out. Groups checked out each element of Corvette ZR1 to make sure cooling and aerodynamics remained high of thoughts, and any change completed the automobile’s mission: efficiency.
Further modifications embrace:
A carbon fiber roof to scale back mass and decrease the middle of gravity for each coupe and convertible
Distinctive aluminum wheel design accessible in 4 finishes, together with Edge Blue — an homage to ZR1’s signature shade cue
Elective new carbon-fiber wheel design, unique to ZR1, to additional cut back mass
LT7 engine consumption completed in Edge Blue — delivering an engine that appears nearly as good because it performs
Elective new carbon-fiber wheel design, unique to ZR1, to scale back unsprung mass by 42.8 kilos
The Corvette ZR1’s cockpit dials up the eye to element, notably with distinctive ZR1 badging discovered on an inside plaque, the sill plates and steering wheel. A brand new ending sew sample for the doorways, particular to ZR1, is out there on the 3LZ trim. A lift gauge can be current, denoting the primary manufacturing facility turbocharged Corvette within the nameplate’s historical past.
Offering additional option to prospects, the Corvette ZR1 will present a roster of customization between exterior and inside colours. Shared with the 2025 Corvette lineup, new colours equivalent to Competitors Yellow, Hysteria Purple and Sebring Orange headline updates. The latter recollects a fan-favorite hue from the earlier C7-generation Corvette ZR1.
Inside, a brand new Habanero inside is out there, as is a Blue Sew choice. Varied full-length racing stripes, brake caliper colours, together with an unique blue for the calipers, seat belt colours and extra can even be accessible.
King of the Hill coming subsequent 12 months
Corvette ZR1 will enter manufacturing in 2025 and will likely be constructed at Basic Motors’ Bowling Inexperienced Meeting Plant in Kentucky. It joins Corvette Stingray, Corvette Z06 and Corvette E-Ray to proceed elevating the Corvette household. Additional particulars on worth and availability will likely be shared nearer to manufacturing.
I wouldn’t be stunned to see a beginning worth within the $175-200K vary, and truthfully given the loopy efficiency that the ZR1 presents, that might be a cut price, undercutting the supercars that it’s completive with by a fairly large margin.
