• The Engine Inside the Acura NSX Is Way More Intricate Than You Thought

The attention to detail is overwhelming

LISTEN 02:38

Supercars are fascinating for a handful of reasons. Their body kits must be both appealing and highly-functional to fulfill tasks that relate to aerodynamics and cooling, while their engines must deliver the best available levels of performance. These aspects, joined by the use of fancy materials and whatnot, make a supercar’s price skyrocket.

However, it’s also the attention to detail that matters in a supercar. Take the Acura NSX’s V-6, for example. Like the powerplants found inside most of its peers, it’s hand-built. The whole process takes place inside a specialized facility spanning over 4,000 square feet, part of the Anna Engine Plant in Ohio.

It’s Not Just a V-6, You Know…


For starters, it’s created exclusively for the NSX. Of course, Acura/Honda needed 12 years to revive the NSX nameplate, so it could not afford any loose ends or untied knots. That’s why the engine gets a bucketload of attention and it’s built to deliver max performance for as long as possible.

Acura’s philosophy was to get the engine as low and as close to the driver as possible.

And since we’ve mentioned the powerplant so many times, it’s only right to look at the specs, too.

So, the twin-turbo 3.5-liter, 75-degree, dry-sump DOHC V-6 makes 500 horsepower (the NSX makes do with a total of 573 horsepower) and 406 pound-feet of torque. It’s also mounted longitudinally in such a way that its highest point doesn’t go beyond the top of the rear tires.

Electric components aside, the engine itself is tuned for lightning-fast throttle response. In this regard, Acura looked a lot at the world of racing when developing the dry-sump system. Even oil is precisely delivered inside the V-6, regardless of temperature and track conditions.

Similar to Mercedes-AMG’s engines, each NSX-bound V-6 is built by a master craftsman, in a single zone, in around five hours.

To put things into perspective, one master builder does, more or less, what 150 people do on Acura’s standard engine assembly lines. Let that sink in for a bit.

Oh, and Acura will do the engine break-in for you at the Anna plant, so when you take the NSX out of the dealer’s parking lot, it’s ready for a launch-control off-the-line start.

Tudor’s first encounter with cars took place when he was only a child. Back then, his father brought home a Trabant 601 Kombi and a few years later, a Wartburg 353. At that time, he was too young to know how they worked and way too young to drive them, but he could see one thing – each of them had a different ethos and their own unique personality. As time went on, he started seeing that in other cars as well, and his love for the automobile was born.  Read full bio
