The concept of good efficient engine is changing all the time. For years downsized engine such as VW Golf was popular in Europe countries. However, there is another way to be efficient. Let's figure out what the difference is.
Once more an brilliant video, thank you very much for your hard work. From my perspective, there is an disadvantage of at least european downsized engines, that they have become very unreliable and problem ridden. Many TSI engines have broken down with engine damages, while others have been noticed for consuming lots of oil. Likewise Fords Ecoboost engines have caused an extreme backlash in northern America and other markets where customers filed lawsuits due to engine fires or mechanical breakdowns. An further downside of direct-injection downsizing engines are carbon buildup on the inlet valves, as they no longer get washed off from port fuel injection. Toyotas latest Dynamic Force Engine hybrids excel also on highways and don't fall short in comparision with diesel engines even. I clearly favor natural aspirated engines from Japan :) On thing to add: Kei cars also use either naturally aspirated or turbo charged engines, both with multi point port fuel injection. I haven't heard of any larger amount of Kei car engine problems, many of them get exported to Russia, Pakistan and lately also to Europe and the US.

Hello! Your comment is very interesting and helpful to understand what's going on in some other countries... We want our cars to be reliable but everything is not going well as we planed in some cases. I thought engine downsizing was kind of ideal in theory but if there are many defects, hmmm it gets us nowhere. I believe that a small Kei car with an ICE is one of the best solution for our environment.

ダウンサイジングが進んでいる4tで 直4 5000ccターボ 210ps/72kg・m直6 9200cc NA 220ps/58kg・m乗りましたが、乗り比べるとMTだとゼロ発進の力強さは大排気量NAの方がよく運転しやすいですね。 加速は小排気量ターボの方が速く感じますね。 最近はAT化が進んでいるのであまり低速の粘りはあまり関係ないかな。
