GM recently dropped the details on the new 2025 C8 ZR1. As an engineer who has worked in both OEM development and aftermarket performance, I’m nothing short of impressed. I spent the last quarter-century bouncing between walking the aisles of the Performance Racing Industry show and releasing engine calibrations that have been driven by millions of unsuspecting users around the world. I have seen lots of 1,000-hp engines. I have had lots of engines go to production after passing emissions, durability, NVH, and safety standards. I haven’t seen very many that did both. Sure, there’s the Bugatti ($3 million and 1,200 hp), the Aston Martin Valkyrie ($3 million and 1,000 hp), and the Ferrari SF90 ($540,000 and 986 hp, combined), but all of these are about as available as unicorn tears to mere mortals. Engines like the Hellephant make over 1,000 hp but have zero chance of passing emissions, so they’ll never be offered in legal roadgoing cars. What we have in the ZR1 is a real accomplishment, and a point where my two worlds seem to have collided.

What Makes the New Corvette ZR1's Engine So Powerful? An Engineer Explains

GM's LS line of V8 engines have been around since the 50s, and powered all sorts of vehicles. Here's every truck the company has made with one under the hood.

The new C8 Corvette ZR1 is a superlatives machine, officially breaking cover late in July as the fastest and most powerful production vehicle to ever fly the crossed flags badge. Of course, all of that speed and performance isn’t without expense, with the new ZR1 expected to carry a six-figure price tag somewhere between $175,000 and $200,000, per a recent GM Authority poll. Interestingly, now-retired chief engineer Tadge Juechter says the C8 ZR1 is the “most expensive Corvette we’ll be doing.”

The 2025 Chevrolet Corvette ZR1 is a monster just ready to terrorize the European elite. It's a mid-engined American supercar with 1,064 horsepower from a twin-turbo 5.5-liter flat-plane V8 engine, and it's capable of a sub-10-second quarter mile. The first units haven't even hit the road yet, but already, John Hennessey is scheming about how to get even more power from America's wildest Corvette ever.

It used to be that an inline four-cylinder was just slightly more powerful than a lawnmower, but modern performance technology, as well as super and turbocharging, has made them formidable engines. In fact, there are some high-output I-4s that rival V-6s and even V-8s, both in horsepower and torque. Gone are the days when four-cylinders were only for sensible compacts, as they now power some of the hottest rides around.

If you have a basic understanding of how a turbocharged engine like the 2023 Toyota GR Corolla's souped-up three-cylinder works, it's not hard to figure out that they pose reliability issues you won't get with a naturally aspirated engine. Before we get into the higher heat and pressure that comes with turbocharging, the bottom line is there are more moving parts, meaning there's more stuff that can break.

Despite the continued development and innovation of combustion engine technology, there will never be anything that can replace the original winning recipe: the naturally aspirated engine. In 2024, we live in a turbocharged and hybrid reality, where the naturally aspirated engine is a dying breed even among specialty manufacturers. What was once a V-8 is now a V-6 with turbos and if you thought inline-fours would forever be the smallest engines on the market, we now have inline-threes making 300 horsepower.

General Motors has released a Customer Satisfaction Program for select units of the GMC Sierra 1500 and GMC Yukon due to an issue with contaminated engine blocks. According to Customer Satisfaction Program N242455301, certain 2024 Sierra 1500 and 2024 Yukon units may have a condition where the engine block of the naturally aspirated 5.3L V8 L84 powerplant may be contaminated. To rectify this problem, certified General Motors technicians will be instructed to inspect affected vehicles and replace the engine as necessary. Notably, this should take GM techs a little less than 20 hours to perform, depending on the exact drivetrain configuration.

The Toyota GR Corolla is a once-in-a-generation car that shouldn’t be thrashed on by anyone but its owner. Perhaps doubly so, given how Toyota has been handling its engine problems under warranty. About the worst thing any GR Corolla owner could imagine, then, is a dealer technician revving the bejeezus out of it on a cold start. Unfortunately, that seems to have just gone down at a Toyota dealer in Boston.
