  • Z06 Specs and Measurements

    Thanks to GM Authority for putting all of these in one place. I believe track width is new to us. Nice we have them corralled here for future reference. Thanks GMA!.

    Here Are The Official 2023 Corvette Z06 SpecsThe new 2023 Corvette Z06 made its official debut this week, arriving with a long list of impressive equipment – including the most powerful naturally aspirated V8 engine ever conceived for a production car.

    While we’ve already covered the 2023 Corvette Z06 in-depth, there are so many impressive parts about the new mid-engine supercar that we figured we’d dedicate a post to going over all of its performance statistics. So without wasting any more time, let’s get into the numbers and see what makes the latest addition to the long-running Corvette lineage so impressive.


    Powertrain


    We’ll start with what is arguably the most important part of the 2023 Corvette Z06: the powertrain. The beating heart of the supercar is GM’s new dual overhead cam, flat-plane crank LT6 V8 engine. This motor has a bore of 4.104 inches and a stroke of 3.150 inches, giving it a total displacement of 5.5 liters. The block is made of A319-T7 sand-cast aluminum and features pressed-in iron cylinder liners and four-bolt main bearing caps and is joined by A356 T6 cast aluminum heads. Output is rated at a GM-estimated 670 horsepower at 8,400 rpm and 460 pound-feet of torque at 6,300 rpm. Power is sent to the rear wheels through a Tremec-designed and built eight-speed dual-clutch transmission, which features a shorter 5.56:1 final drive ratio in the Z06.
    RPO Code LT6
    Bore x Stroke (in / mm) 4.104 x 3.150 / 104.25 x 80
    Block Material A319-T7 sand-cast aluminum with pressed-in iron cylinder liners and four-bolt main bearing caps
    Cylinder Head Material A356 T6 cast aluminum
    Valvetrain DOHC, 4 valves per cylinder
    Fuel Delivery Exhaust side direct injection
    Horsepower (hp / kw @ rpm) 670 / 500 @ 8,400 rpm (GM est.)
    Torque (lb-ft / Nm @ rpm) 460 / 623 @ 6,300 rpm (GM est.)
    Transmission Type M1L 8-speed dual clutch (DCT)
    Final Drive Ratio 5.56:1

    Suspension


    Now let’s move on to the suspension. The 2023 Corvette Z06 is underpinned by short/long arm double wishbone suspension in the front and rear with forged aluminum upper and cast aluminum L-shaped lower control arms and monotube shock absorbers. Magnetic Selective Ride Control 4.0 is available, with Z07 Performance Package models receiving their own unique Magnetic Ride Control calibration. The steering system is made up of a variable-ratio rack-and-pinion with electric power assist and a 15:7:1 steering ratio. Models with Magnetic Ride Control also include Active Steer Stops.
    Rear Suspension Short/long arm (SLA) double wishbone, forged aluminum upper and cast aluminum L-shape lower control arms; direct-acting stabilizer bar; monotube shock absorbers (46mm); Magnetic Selective Ride Control 4.0. Specific calibration with available Z07 package
    Steering Type Variable-ratio rack-and-pinion with electric power assist; includes Active Steer Stops with available Magnetic Ride Control 4.0
    Steering Ratio 15:7:1
    Brakes


    Brembo six-piston brakes sit out front, which grab 14.6-inch two-piece rotors. Residing out back are a set of Brembo four-piston calipers, grabbing a set of slightly larger 15-inch rotors. Carbon ceramic brakes are available via the Z07 Performance Package, which feature the same Brembo calipers, but larger 15.7-inch and 15.4-inch front and rear carbon rotors.
    Rear Brake Type eBoost-assisted discs with Brembo four-piston/monobloc calipers
    Front Brake Rotor Size (in / mm) 14.6 x 1.3 / 370 x 34
    Front Brake Rotor Size (Carbon Ceramic) (in / mm) 15.7 x 1.5 / 398 x 38
    Rear Brake Rotor Size (in / mm) 15.0 x 1.3 / 380 x 34
    Rear Brake Rotor Size (Carbon Ceramic) (in / mm) 15.4 x 1.3 / 390 x 34

    Wheels


    The 2023 Corvette Z06 rolls on staggered wheels measuring 20 inches by 10 inches in the front and 21 inches by 13 inches in the rear. The front tire size is 275/30ZR20, while the rear tire size is 345/25ZR21. The wheels come shod in Michelin Pilot Sport 4S ZP tires, although stickier Michelin Sport Cup 2 R ZP rubber is available via the Z07 pack.
    Rear Wheel Size 21-inch x 13-inch (w/ 5 x 120mm bolt pattern)

    Rear Track (in / mm) 66.1 / 1,678

    Interior


    The interior dimensions of the Corvette Z06 are mostly the same as the Stingray on which it’s based. It has 37.9 inches of headroom, along with 42.8 inches of legroom, 54.4 inches of shoulder room and 52 inches of front hip room.
    Legroom (in / mm) 42.8 / 1,087

    John, have you verified the accuracy of this data? "...monotube shock absorbers. Magnetic Selective Ride Control 4.0 is available..." I thought they said MRC is standard.

    I thought you posted the specs from a press release.

      Both are true. The are magnetorheological (mag ride) monotube shocks.

        It should be noted that for first time they are quoting DRY weight instead of CURB weight with fluids, like previous Corvettes. (They used to criticize Ferrari for doing this). We might have to wait for the magazines to weigh their press cars to find the actual weight.

          Well…, not. Note here are from 7.18.19 9 from the 2020 C8 Media.Chevrolet identical press page. When therefore compares apples and oranges, the dry weight of the C8 Stingray was 3,366 and the dry weight in the Z06 spec sheet last week was 3,434, a difference of 68 pounds.

          Yes, years ago GM used to criticize Ferrari for using dry weight but not that all have gone that way, GM has too.

              We do not yet but I submitted a request for that specific information to GM last Tuesday. I know they ahve been beyond super busy. As soon as I hear, I will prominently post either in its own thread or more like within our Z06 Wheel Thread.
