2020 RLX Performance

There's good performance on offer from the only available engine (a hybrid model is available as well but this is reviewed separately). The RLX's 3.5-liter V6 engine does without turbocharging but still has acceptable outputs of 310 horsepower and 272 lb-ft of torque. Paired with a quick-shifting ten-speed automatic transmission, the combination is enough to see off the 0 to 60 mph dash in six seconds on its way to a 155 mph top speed. Sending power to the front wheels only, the RLX can't match the rear-wheel-drive thrills or the ultimate all-wheel-drive traction offered by several competitors. And, although the V6 engine is solid, there's simply more choice in rivals' model lines so the Acura's appeal remains limited.

Engine and Transmission

The 3.5-liter V6 engine has been employed in several other Acura models and for good reason: it provides decent power, sounds good, and is reasonably efficient. The i-VTEC (intelligent Variable Valve Timing and Lift Electronic Control) unit has peak outputs of 310 hp and 272 lb-ft of torque. Earlier RLXs used a six-speed automatic transmission, but this model gets a ten-speed auto that is not only 22 pounds lighter, but with a 68 percent broader ratio range. It works well, shifting through its many ratios smoothly and quickly, while high-speed cruising is a relaxed affair. The big Acura gets off the mark with enough vigor and the transmission's ability to execute four-gear direct downshifts (from tenth to sixth, for example) improves overtaking flexibility. While the naturally-aspirated engine has typically linear power delivery, you do occasionally miss the instant mid-range grunt you'd get with a turbocharged unit.

2020 RLX Gas Mileage

Providing decent gas mileage figures, the V6-powered RLX's EPA estimates work out to 20/29/23 mpg on the city/highway/combined cycles. The gas tank size is 18.5 gallons and when topped up with premium unleaded, should see the RLX managing a combined cruising range of around 425 miles. For more efficiency, the hybrid RLX will achieve an extra five miles-per-gallon in mixed driving conditions.
