We are classifying this next story as a rumor since the European C8 exports has yet to officially start, but thanks to a German Corvette enthusiast, we are learning that the European Emissions laws may have a real effect on the C8 Corvette’s horsepower.
We recall this 2019 story that when these new emissions rules went into effect in September 2019, GM was forced to halt the sales of the 6.2L V8 Corvettes and Camaros in the European Union as it required existing vehicles to be recertified under the new standards. GM elected not to recertify the Camaro due to its small sales figures and the C7 Corvette was soon to be retired for the C8 Corvette.
Part of these new emission laws had to do with the requirement of “Gasoline Particulate Filters” on engines that utilize direct injection. According to an MIT study posted in 2015, “GPF will create an additional back-pressure in the engine exhaust system that will reduce engine power and efficiency. This back pressure will increase as PM is trapped in the filter and decrease as combustible PM removed.”
A senior contributor to the MidEngineCorvetteForum.com named Ace who lives in Germany tells us that he has confirmed with multiple European dealers and even shares what the new horsepower, torque, and the expected 0-60 mph performance figures will be with the gasoline particulate filters on the LT2 V8:
Just got the information and confirmed that with multiple dealers that the European Corvette will have reduce in overall power thank to the requirement to install a Gasoline Particulate Filter to meet EU emission laws. The power changes as follows:
Horsepower: 468 HP (down from 495)
Torque: 455 Lb-ft (down from 470)
0-60 mph: 3.5s (down from 3.0)
To me this is a huge let down since the European C8 prices are pretty high compared to the US market (even though 2LT Z51 is standard here).
