Last week, a handful of leaked General Motors documents sent the internet ablaze with speculation. Said documents seem to have confirmed an incoming 6.2-liter LT5 DOHC V8 engine for the 2018 model year of Corvette.
Pinpointing the engine was possible by following a few GM codes in a GM North America engine table, which showed the LT5 engine code pairing up exclusively with the Corvette for 2018. So, it seems all but officially confirmed the Corvette will be gaining a DOHC V8 engine in a little over a year’s time.
This fueled today’s Community Question: are you looking forward to a DOHC V8 engine for the Corvette?
It’s not the first time a DOHC V8 made its way under the hood of a Corvette. Those familiar with the C4 Corvette ZR-1 will remember its 5.7-liter V8 engine, also called the LT5, was a DOHC design developed with Lotus. That engine helped give birth to a monstrous Corvette, producing 375 hp in 1990.
DOHC has its advantages over GM’s long history with pushrod V8s, including the ability to breathe easier and rev higher. The average Corvette consumer may not care about the pushrod vs. dual overhead cam argument, but purists will most certainly cry foul.
We don’t know specifics about the upcoming LT5 V8 engine, or which variant of Corvette will receive it (though the 2018 Corvette ZR1 is a likely contender) and it’s unclear if any sort of forced induction will be present, but we do know it will be a radical powertrain change the Corvette hasn’t seen in quite some time.
With that, it’s your turn to sound off. Express yourself in the poll below and strike up a conversation in the comment section below.
