10 Of The Most Reliable Toyota Engines Ever Built, Ranked

Toyota has long been an industry standard bearer in the automotive performance world. Toyota represents one of the best-selling brands in the United States, with a roughly 15% market share overall and more than 2 million vehicles sold in the U.S. in 2022.

Between its electric vehicle offerings and ICE heritage models that date back decades, Toyota has routinely been in a leadership role in building and selling quality cars. Toyota isn't just a commuter or truck brand, though — the company produces some of the most reliable models on the road today. 

This starts with the engines that power both modern and vintage Toyota examples. The cars produced under the Toyota badge (and those owned by Toyota Group) are propelled by some of the most technologically advanced and ruggedly reliable motors that have ever left an automotive factory floor. These are the most reliable examples of Toyota engines that have ever gone under the hood.

10. 1LR-GUE V10

Starting off the list is the 1LR-GUE. This is a V10 model that was produced specifically for a single, limited-run production model, the Lexus LFA (debuting in 2009). The V10 is a work of art and was hand-built. Its uniqueness isn't found in the typical production engine -– especially from one of the world's largest brands.

The engine was explicitly created to underpin the performance metrics of the Lexus LFA model that had emerged from the research and development team as the brand's flagship performance vehicle. To generate the allure Toyota sought in its Lexus supercar, the team partnered with Yamaha to develop a highly technical engine that showcased stunning performance metrics and sounded fabulous when a driver laid on the gas pedal. 

The result was a 4.8L V10 that put out 552 horsepower and 354 lb-ft of torque. The engine was naturally aspirated and could push the car to a top speed of 202 miles per hour with a 0-60 time of just 3.7 seconds. What sets this V10 apart from the typical muscular engine is its engineering and construction. The production is built from lightweight materials and employs a compact design – including a 72-degree angle between the cylinder pairs. This makes it weigh in around the same as a V6 and occupy the space of a V8. The technology that went into the design of the 1LR-GUE engine made it a reliable and high-performance powerplant that is still discussed today.
