Car and Driver‘s Don Sherman has been at the forefront of mid-engine Corvette news since the first mock-up prototype was spied. Today, it’s all about the transmission.
The latest report from Car and Driver cites Tremec’s acquisition of Hoerbiger Drivetrain Mechatronics, responsible for relationships with Mercedes-AMG, Ferrari and McLaren. Now, the engineering expertise from both Tremec and Belgium-based Hoerbiger has given birth to the TR-9007 family of dual-clutch automatics.
The report goes on to state the inbound mid-engine Corvette is evidence of the DCT’s testing and goes on to spec the gearbox to withstand a redline of 9,000 RPM and 664 lb-ft of torque. As for further technical specs, the transmission uses typical helical gears found in DCTs and Tremec engineering documents state the TR-9007 contains seven forward gears. Three of those are overdrive ratios, and the transmission features a 5.6:1 ratio spread.
If Tremec’s latest masterpiece is indeed going to be found in a mid-engine Corvette, you can more than likely kiss a manual gearbox option goodbye. The cost to engineer and fit two different transmissions will likely outweigh the benefit of offering a standard row-your-own.
