Explained: Why do Toyota engines last for more than 10 lakh kilometers [Video]

Every car manufacturer who sells car in India has a USP. This is what separates each of them from the others. While there are some who focus on the fuel economy, there are other who stress on the build quality of the cars. There are even a set of manufacturers who are like by customers because they offer several features with their cars. Toyota as a brand is popular among buyers for its reliability. Toyota engines are known to be extremely reliable. Several type 1 Innovas that are still running on our road without any major problems are a testimony to the same. Here we have a video that explains why Toyota Innovas are extremely reliable when compared to other cars in the segment.

The video has been uploaded by Talking Cars on their YouTube channel. The video shows a 2.5 litre turbocharged diesel engine that was once available with Innova. The video explains what makes the Toyota engine so special from others in the segment. The engine is built to a purpose. Unlike engines that are available in many modern cars, this engine does not have too many advanced functions. Toyota ensured that they get the basics right while building this engine. It gets a cast iron block with aluminium pistons and aluminum head.

Unlike some manufacturers, Toyota never aimed to make engines lighter and save weight for better fuel efficiency. The main motive of this particular engine was to last longer. Toyota has also not compromised on the quality of the materials they used in this engine. The connecting rods of the aluminum pistons are strong and build to last longer. Along with basic engineering, Toyota made minor changes to ensure that the pistons remain cool even when the engine gets warm. This in turn resulted in less wear and tear in the longer runs.

The 2.5 litre D4D engine used Toyota Innova MPV was designed in such a manner that it generated higher torque at lower revs. The engine would redline at around 4,400 rpm. Innova generated 100 Ps and 200 Nm of torque which was less when compared to other vehicles using the same capacity engine. For example a Maruti Ertiga 1.3 diesel was generating same amount of torque as the Innova with a smaller engine. Toyota could have tuned the engine to generate more power and torque but, that was never the priority.

The aim at Toyota was to tune the engine is such a manner that the engine is neve stressed. Once the engine is tuned to generate more power and torque, it would strain the engine a lot and that would in turn result in showing errors issues and would not last as long a regular Toyota engine. Engines used in Toyota Innova is a perfect example on how a diesel engine should be. The engine was imported from Thailand and the build quality, fit and finish of this engine was way better than anything else that was available in the market at that time. Toyota’s engine shows quality of components and precision plays a crucial role while building an engine that is meant to last very long.
