Last week we brought you the news that the 2020 Corvette Stingray didn’t win Road & Tracks coveted Performance Car of the Year award and that the main culprit that lead to the mid-engine ‘Vette’s demise was the new dual-clutch transmission.
Well, Corvette fans, Road & Track is back this week with tidings of great comfort and joy! In a new piece entitled, “How the C8 Corvette’s Dual-Clutch Has Changed Since We Drove the Car” penned (typed?) by Chris Perkins, they remind us that the car they tested was a pre-production model and that the final product will be much improved.
Challenge of the day: try not to fall asleep when reading the next sentence. Last week Chevrolet held a powertrain engineering seminar where R&T was able to catch up with Glen Hoeflinn, controls program manager for the DCT. When asked about the Dual-Clutch’s current state, Hoeflinn said, “Maybe you get some humpy-bumpy shifts here, you get a little bit of that there. That all gets refined out… It’s in final refinement, and then it’s in final checks and looking what we’re doing and making sure that it’s behaving exactly [how] we want… That’s what we’ve done since the car that you had. Doing all that refinement and making sure it’s ready to go for everybody across the all the cars.”
He continued by speaking on the challenges of making a good DCT, “There’s a lot of pre-selection interaction that goes on in the background, It’s the same choreography between the engine and transmission but without the “luxury” of a torque converter, there’s a lot more programming work involved.”
The article goes on to point out the unique aspects of the C8’s dual-clutch transmission; it really is a great read if you are into that sort of thing, we recommend checking it out for some peace of mind about the future of the DCT (we have the utmost confidence that the final version will be world class!).
A final note of interest came when R&T concluded the piece by helping us continually put a bug in the Corvette Team’s collective ear about a desire for a manual transmission. Of course, the usual corporate lines were given: shrinking market, expensive, blah, blah, blah but with any luck they will eventually cave to our demands like tired parents of persistent, annoying children. Keep pestering, Corvette Nation!
