TOP 5 Reliable Car Engines in Modern Vehicles

Here are our TOP 5 reliable car engines you can see under the hood of modern cars.

Probably few people would think to challenge the fact that modern car engines are more reliable, fuel-efficient, and refined than older ones. In newer vehicles, computer-controlled electrical components have taken the place of many mechanical parts.

Engines in modern cars can go longer between service intervals. There are more and less reliable engines in terms of engineering, but of course, a lot depends on HOW the vehicle is operated. No matter how good and reliable the engine is, if we mock it, it will fail sooner or later. Here we’ve mentioned some of the car engines which do their work well and have a high reputation for reliability.


Toyota deservedly leads the reliability ratings for years. A 2AR-FE unit is one of the brand’s most economical engines ever. Its simplicity is the key to reliability, and the number of basic AR-specific defects is extremely small.

This engine is an inline four-cylinder with an aluminum DOHC* head and a die-cast aluminum engine block. For better fuel economy, it incorporates a new technology: dual VVTi or Variable Valve Timing with intelligence on both intake and exhaust. The 2AR-FE applications power such Toyota models as the Camry, RAV4, Alphard, or the Scion TC.

General Motors introduced the LS family of small-block V8 and V6 engines in 1997, and since then, thanks to evolution over the years, they have gained a high reputation.

The LS V8 (upper photo) is one of the most popular 8-cylinders ever. V8s were and still are available as crate engines, in LS3, LS376/480, and LS376/525 variants, which produce no less than 430 horsepower and 425 pound-feet of torque. The sixth generation is around the corner.

Maintainability is one of the advantages of the LS engine, as part replacement is not a problem. The LS- family engine power Chevy’s iconic models, like the Corvette C7, C8, ZR1, Z06, or the Camaro SS and ZL1. It is installed on the Silverado and Chevrolet’s full-size SUVs, as well as Cadillacs, like Escalade-V and CT5-V Blackwing.


The Porsche brand has a reputation for being innovative and dependable. Really, both its vehicles and engines can last a lifetime if properly maintained. A used Porsche is still a decent investment: it’s a good car that keeps value well.

An M96 engine is great, and the Porsche 911 (996) owes its popularity to the engine, in many ways. A guy Tom Thalmann drove his 996 Turbo to 647,000 miles (1,087,916 km). The 996 shows up well with a twin-turbo 3.6-liter M96 flat-six that delivers 414 hp and 415 lb-ft of torque.
