This week the annual SEMA aftermarket show is going on in Las Vegas. Acura has decided to join the fray this year by showing off a modified 2019 RDX that packs an impressive 345 horsepower. This particular RDX went under the knife with Graham Rahal Performance.
Graham Rahal is a natural fit to tune a Honda-based product. He already races for Honda in in the IndyCar series, so having his performance company work on this RDX was probably an easy choice.
From the outside, this modified RDX does not look significantly different from the production RDX A-Spec. There’s a revised lower fascia design up front, blacked-out badging and unique wheels. Of course, there’s also a host of graphics, because SEMA. Carbon fiber accents on the mirrors and other trim pieces round out the look.
The more interesting elements of this RDX rest under the hood. Graham Rahal Performance has taken the RDX’s turbocharged 2.0-liter and swapped out the turbo, intake and exhaust manifold. KTuning also wrote a new ECU tune for this vehicle. Collectively, the combination of private label and off-the-shelf parts allows the 2.0-liter to jump from 272 to 345 horsepower.
It’s hard to say if Acura has any intentions of building a hotter RDX. Given the base version is quite good with 272 horsepower, it seems like a natural progression for the vehicle. Time will certainly tell. In the meantime, you can see this RDX at SEMA.
