Pop quiz: Whatís the most powerful Acura offered today?

If you said NSX, the Japanese luxury brandís hybrid supercar, youíre spot on. But do you know which of its other five other models comes second in this under-hood arms race? Thatís a tougher question to answer.

Not to leave you twisting in the wind, itís actually the RLX Sport Hybrid, a partially electrified version of Acuraís somewhat forgotten large car. With a 377-horse stable, itís also the companyís most powerful sedan ever, though the 196-pony chasm between it and the NSX is broad enough to make the Great Plains blush.

Spacious yet unexpectedly economical, this four-doorís design has been spruced up for 2018 and its hybrid drivetrain further refined. Helping potential buyers, its trim structure has been greatly simplified as well, which should help demystify the shopping process. Properly sized and equipped, the company fancies it a foil to models like the Audi A6, Lexus GS, and BMW 5 Series, to name a handful of potential competitors.
