GM Confirmed That The 2018 Corvette Comes With The New LT5
Corvette had the last DOHC engine back in 1995. It evaded the technology since, but it seems we may see the DOHC engined Corvette as early as the next year. In a leaked dealer document which turned out to be a vehicle identification number (VIN) guide, GM did link the LT5 engine with the Corvette. It should come for the 2018 model year, but that is all we have to go on for now. However, a 6.2 liter DOHC V8 with direct injection, VVT (variable valve timing) and an aluminum block could be the best fit for the mid-engined Corvette we have heard so much about in recent months.
What we certainly know is that the new engine won’t replace the LT1 from the Stingray. That one is also confirmed for 2018, so it seems that only a mid engine ‘vette or the ZR1 might get the DOHC. As these engines tend to rev higher compared to the OHC units, we assume, it’ll go to the mid-engine model. After all, every exotic car has an engine there and all of them rev their lives out. Just for comparison sake let’s point out that the V10 in the Audi R8 can rev up to 8,700 rpm. Sick.
On the other hand, the LT5 could end up in the ZR1 and in the mid-engine ‘Vette too. Think about it, we can expect an exotic Corvette in 2019, while the ZR1 has to come next year. So, while GM sharpened it up in the ZR1, the LT5 engine will be finally ready for the mid-engine car as well.
One major question remains unanswered! Is this a naturally aspirated engine or a supercharged/turbocharged one? Considering the LT4 already gives out up to 650hp for the Z06, we have to assume the ZR1 will join the gentleman 700 club with the F12 Berlinetta and the Aventador. It has to, although it does not represent direct competition to the Italians. In that case, we find it hard to believe that GM will make it only naturally aspirated. Some kind of forced induction has to be in place. Yet, they did not mention anything about it in the document.
Nevertheless, GM will reveal new information in the coming months (if not weeks) and we will be ready. It may be that we see the 2018 Corvette ZR1 at the NAIAS in January. With the LT5 under the bonnet!
