The National Corvette Museum is holding its Bash event this weekend to officially kick off the 2013 season as well as the 2014 Corvette C7, and one of the official details that was revealed yesterday (besides C7 pricing info) was that the 2014 C7 coupe without the Z51 package has an estimated curb weight of 3,298 pounds (1,496 kg) — or 90 pounds (41 kg) heavier than the 2013 C6 coupe’s 3,208-pound (1,455 kg) curb weight.
Here are the detailed mass reductions and additions to the C7. Keep in mind that these may not be all-inclusive:
Areas Of Mass Reduction
- Frame: 99 pounds lighter
- Body panels: 37 pounds lighter
- Hatch: several pounds lighter
- Control arms: now hollow, several pounds
Total weight savings is in the vicinity of 150 pounds, or 68 kg.
Areas of Mass Addition
- 35.2 pounds — direct injection, VVT, AFM
- 6.6 pounds — standard engine oil cooler
- 13.2 pounds — dual mass clutch
- 15.4 pounds — steel torque tube part of AFM
- 5.5 pounds — AFM exhaust valves
- 11 pounds — 7th transmission speed
- 18.5 pounds — strengthened differential, half shafts
- 18.3 pounds — larger fixed brakes
- 17 pounds — new interior appointments and safety features
- 17.2 pounds — upgraded seats
- 18.5 pounds — structural safety requirements
- 31.5 pounds — new infotainment and cabin technology, as well as relocating battery to the rear
- 3 pounds — bigger fuel tank
That’s a total weight gain of 210 pounds, or 95 kg.
Opting for the Z51 performance package would add transmission and differential coolers, a rear sway bar, larger wheels, electronic differential, and a spoiler. Although unconfirmed, these changes will most likely result in the addition of 150-200 pounds.
The GM Authority Take
As it stands, despite the various weight-saving technologies and components, the 2014 Corvette C7 is heavier than the outgoing C6. It’s not heavier by much… but it is still heavier… while being more capable, refined, and luxurious than the outgoing model.
