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.

Reliability Showdown: Turbocharged Vs. Naturally Aspirated Engines

In the 1980s, many racers were experimenting with turbochargers on stock engines. Colossal horsepower and torque numbers could be produced for a short period until the engine self-destructed. One of the weakest links they focused on was how to keep the head attached to the block under extreme pressures. Many engine builders experimented with copper gaskets, deck plates and other solutions to solve head gasket failures.

Dodge has ignited a firestorm by introducing the world’s first battery-electric muscle car, the 2025 Charger Daytona. This daring move from Dodge simultaneously embraces the electric future while paying homage to the brand’s combustion engine legacy. Offered as both a two-door coupe and a four-door sedan, the Charger Daytona caters to a diverse audience.

Dodge Revolutionizes Muscle Cars with the 2025 Charger Daytona: A Bold Leap into the Electric Future While Honoring Combustion Heritage

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

The automotive world is mourning the loss of a legendary powertrain. General Motors has confirmed the impending retirement of its celebrated 3.0-liter inline-six Duramax diesel engine. Renowned for its exceptional torque delivery, commendable fuel efficiency, and formidable towing capacity, the Duramax has been a cornerstone of GM’s full-size SUV lineup.

The 5.4-liter Ford Triton V8 engine doesn't exactly have a stellar reputation, but it powered cars and trucks for long time. They can't all be bad, right?

Every Ford Model Powered By The 5.4L V8 Engine

While the world moves more and more towards an eco-friendly future, certain aspects of the automotive industry suffer. As emission restrictions tighten and Corporate Average Fuel Economy (CAFE) metrics become harder and harder for manufacturers to meet, engine sizes are becoming smaller in order to meet those goals. That's why we've seen so many six-cylinder engines drop to four-pots, while V8s have been downgraded (or upgraded depending on where you stand) to twin-turbocharged sixes.

Toyota's Most Powerful 4-Cylinder Engine

Since being introduced in 1989, six-cylinder Cummins diesel engines have enjoyed years of success. In addition, the 6.7L Cummins I6 is a good engine, earning high levels of owner satisfaction while powering several generations of Ram pickup trucks since 2013, and given the dominance of the Cummins 5.9L 6BT and its 6.7L I6 turbo diesel replacement, it's understandable if you find yourself asking if Cummins even makes a V8.

Toyota has issued a major recall of its twin-turbocharged V-6 engines powering the 2022 and 2023 Tundra pickup trucks and Lexus LX SUVs. Engines produced between late 2021 and early 2023 might have machining debris left in the engine; causing engine knocks or, worse cases, a spun bearing and complete engine stall. At first, Toyota was unsure how many engines were contaminated, but now, months later, the solution is to replace more than 100,000 engines.

11 Affordable Used Cars That Have Engines Just as Good As New

There are many car maintenance tasks that you can do yourself without much difficulty. An important one is cleaning and maintaining your car’s air filter. This filter is important because it allows air to combine with your fuel to cause combustion and power the engine. If the filter is dirty and not taken care of then this can greatly impact the car’s performance. Instead of paying a professional to clean it or replace it entirely, you can clean it and put it back in yourself if it's still in good condition. Here is a detailed guide on how to clean an engine air filter.

With its production run spanning four decades, and eight generations, the Pontiac Grand Prix was among the GM-owned carmaker's most popular vehicles. For most of the decade after its 1962 introduction, Pontiac positioned the Grand Prix as a full-size performance coupe. Over successive generations, however, the car would undergo several transformational changes, culminating in it eventually becoming a four-door sedan by the time its production run ended in 2008. Well over a decade since the last Pontiac Grand Prix rolled out of the assembly lines, the car is still very much in demand — especially the older variants of the car dating back to the '60s and '70s.

What Engine Is In A 1989 Pontiac Grand Prix & How Much Horsepower Does It Have?

Electric automotive technology isn't necessarily a new thing, but it has become substantially more popular in recent years as brands push to lower their overall carbon footprint. A conventional electric car design possesses far fewer moving parts , making the overall drivetrain a lot more efficient when compared to your average ICE design. Couple this with the fact that you don't need any fossil fuels to power an EV, and you'll find that this newer technology is a lot more of a logical choice for new automotive designs. Of course, this puts the debate of which configuration is more enjoyable to the side, as EVs generally have a reputation for being dull and soulless.
