  • European C8 Corvette will lose close to 30 HP!

    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).

    Thank you though that is disappointing news not reported anywhere else so please, which dealers confirmed this news please for we have not heard word one about it. It must be a new Euro requirement for there were no such losses in previous generations.

      Not sure if they do regular inspections, but seems like something that we'd just remove after purchase in non E check states here.

        Might not be that simple if the software/tuning is designed for it to be installed.

          Thanks, Ace for this info!

          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.

            Ah, the irony. It was a couple of decades ago that the European cars were much more powerful and the ones we got in the U.S. were detuned to meet U.S EPA regulations. --Bob

              What happens to the fuel that passes through the "Fuel Particulate Filter" to reduce power?

                Its a particulate filter in the exhaust system.

                    european union flexing its muscle on emissions seems to promote electric vehicles more and more everyday. Tesla seems to be selling quite well and more and more vehicles are going hybrid or full ev to even be allowed in certain cities.

                    the funny part is countries like china pollute their enviroment at full speed ahead and that pollution travels around the world anyway...

                    that particle filter costing 30 hp isnt going to amount to a jack when taking into account the amount of pollution countries like china or India are polluting.

                    glad the Europeans are trying to find solutions. Their solutions are in my opinion foolish. Ban chinese goods with a tarriff to pay for solar power or like frances nuclear powerplants.

                    then just launch the nuclear waste far off into space one day?

                    i dont know much about any of this but not inowing if the particle filter can be removed without upsetting the pcm is an unknown. Id imagine some aftermarket company will create a solution...like a free flowing dummy filter cartridge etc

                    fear not...someone will find a solution and the next thing you know the european c8 will produce 50 more hp than the US version for as little as $100 ...

                    just the nature of the beast...id be more concerned the exhaust roar of the v8 was muffled

                      I saw an article not long ago that projected China would be producing more than 1/2 of the world's CO2 by 2030. In 2013, they were "only" contributing 28% of the worlds CO2 emissions. https://dotearth.blogs.nytimes.com/2...-climate-path/

                      Check out their CO2 growth rate since 2003.

                        Correct. The new Porsche GT3 has a dummy restrictor in the exhaust of the US version so that they didn't have to totally redo the engine tuning for the US version.

                          The only articles I can find online all trace back to this thread. But I find it believable. Many euro gasoline cars are using these now, including new Porsches, and they do restrict exhaust flow.

                            There is actually much more to this than the newsmagazines copy-pasted from each other. In September 2018 the new WLTP emission regulation laws came into effect that included stricted rules than before. But it was not like they came unannounced, it was known to the public that the laws came in 2018 for 3+ years. Compared to Ford with the Mustang Chevy decided to not modify the Camaro or Corvette to meet the new regulations (which had nothing to do with engines sizes, it also effected the 4 cyl Camaro), they got just an exception to be able to sell the prebuild cars until September 2019 - That's why we still got the pre-fresh model then even though Chevy already build the 19 model in usa. But it was no ban of V8 or what some magazines wanted to sell.
                            But they are still selling new Camaros again. They are not EU models, but imports from USA that are sold through Chevy USA, so they only have to meet easier emission laws that are affecting imports.

                            But what really bothers me is that Ford is able to sell the Mustang with pretty similiar power then the US models even though it also has a GPF, but Chevy somehow loses 30hp for the C8.

                            Yeah, also you will have upcoming problems when going to the necessary emission test every 3 years. And since your car is polluting more CO² you are legally attackable with a tax fraud claim. and you car loses it's street legality including insurance.
                            We would wait for tuners to give the EU C8 a powerbump that is legally accepted through them, but it will be easiy 3k€ plus losing your warranty to get the horsepower back.
