● About this selection
There are 44 engines that have won admission tickets for this selection, two of which are returned from last year’s winners— — Honda’s 3.5-liter V6 naturally aspirated engine and Audi’s 3.0-liter V6 turbocharged engine. Of course, these two models are still young and continue to win awards this year.
Judging from the selection results, eight out of ten companies use direct injection technology, and six of them are equipped with turbochargers. It seems that these two key technologies to achieve small displacement and large work strategy have become a fact that they are sought after by various manufacturers. Let's take a look at the specific advantages of each engine. (In no particular order)

Counting this year, Audi’s 3.0-liter V6 supercharged engine has won the top spot for five consecutive years. This engine is currently installed on the Audi S5. For the past five years, there have been many V6 engines that have entered the market back and forth, but there are very few that can truly compete with Audi's power. The latest engine that has also been on the list for five consecutive years in the Ward engine competition is still the 2.0-liter L4 turbocharged engine from Audi, which is mounted on the Audi A4. The award period is 2006-2010.
● BMW 3.0-liter L6 diesel supercharged engine
This engine is improved from the old version in 2009 and 2010, mainly It replaces the original twin-scroll single turbocharger with a variable-section turbocharger. Although this change is slightly weaker than the old model in power, this engine has a better advantage in improving fuel economy. The current models equipped with this engine are 535d and X5.BMW 535d Sedan 3.0-liter L6 diesel supercharged engine parameters Maximum output power (kw/rpm) 188/4000 Maximum output torque (Nm/rpm) 560/1500 Number of valves per cylinder (pcs) 4 valve type DOHC cylinder arrangement In-line 6-cylinder working mode Supercharged cylinder volume (ml) 2993 displacement (L) 3.0 compression ratio 16.5:1 engine-specific technology Engine start-stop technology Fuel supply mode Diesel common rail direct injection in-cylinder official comprehensive fuel consumption (L) 6.7 Official acceleration time to 100 kilometers (s) 6.4 Maximum speed (km/h)--
The peak torque of the engine has appeared at 560 Nm at 1500 rpm, which can effectively suppress turbo lag at low speeds. In terms of fuel consumption, the 535d Sedan has a fuel consumption of 6.7 liters per 100 kilometers, which is even better than some four-cylinder diesel engines.
