As a larger engine is usually able to burn more fuel and produce more power than a smaller one, a car with a larger, more powerful engine is likely to be able to accelerate faster and tow heavier loads than a car with a smaller engine can manage. This rule of thumb is less accurate today than in the past.

Diesel engines

Why do large-displacement American V8s generally produce less horsepower per liter of displacement compared to their European and Japanese counterparts? A common answer is that American engines are tuned to favor low-end torque instead of top-end horsepower, but that answer is vague and only half true.

Larger engines will generate more torque. That allows the use of a transmission that lets the engine run slower for the same given car speed. So while a four-cylinder engine might turn at 2,500 rpm at 65 mph, an eight-cylinder engine might turn at 1,800. That could contribute to longer life.

Displacing 2.4 liters in an inline-four configuration, the LEA is part of the Ecotec engine family. It features direct injection, variable valve timing, and is capable of running on E85 fuel….GM 2.4 Liter I4 Ecotec LEA Engine.

The standard TLX engine is anything but standard. The aluminum block direct-injected 2.4-liter inline-4 powerplant delivers 206 high-revving horsepower 81 at 6800 rpm, 182 lb. ft.

Engine life is a function of load and RPM. However if the engineering and quality were equal, then the larger engine should theoretically last longer. This is because it doesn’t have to work as hard as a smaller engine, and therefore the parts won’t have as much stress on them and won’t wear as fast.

These are the longest-lasting car brands for 2020. Automotive search engine iSeeCars.com analyzed more than 15.8 million car sales in 2019 to identify which brands build the longest-lasting cars. The company found that models from Toyota, Honda, and GMC were the most likely to last for at least 200,000 miles.

The car with the engine running at a lower RPM (the V8) to deliver the same HP output will outlast the V6 that runs at a higher RPM in terms of wear and tear, Outlast means probably a higher mileage for the V8 before a reconditioning is required.

Frequent motorway trips Bigger engines can better handle the rigours of the motorway – such as overtaking. And because bigger engines are built for higher speeds, you may well find them to be more fuel-efficient than smaller-engined cars, since they won’t be put under as much strain.

In general no . Small displacement engines work harder and so are stressed more . But that is not the whole story . The reliability of an engine is measured by the auxiliaries .

By revving harder and therefore working harder, smaller engines can match bigger engines for power. A two-litre four, for example, will produce the same power as a four-litre V8 when it’s revving twice as hard as the bigger engine, provided it’s equally efficient.

So for example if it is an 1.4L 4-Cylinder engine each cylinder has an volume of . 35L or 350mL. 1.4 or 1.6 litre simply means the volume of working fluid taken in by piston during suction period. So large displacement engines means more power but less mileage.
