While exterior styling and interior comfort are all well and good, an engine is what really defines the character of a car. What is the best engine of the last 20 years? And why is it so great?
There are just so many aspects of an engine that make them great. Maybe it's the insane engineering prowess behind some that make them rev to 9,000 RPM. Maybe it's how they were packaged to fit in a tight engine bay. Maybe it's the use of special materials or techniques. Or maybe it's just how they sound.
What do you think is the greatest engine of the last 20 years? And with your answer, we want to know why you chose that engine. Is it the character under acceleration? Is it the tech? Something intangible? We need to know.
