The RLX has standard whiplash protection, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the whiplash protection system moves the headrests forward to prevent neck and spine injuries. The Taycan doesn’t offer a whiplash protection system.

To help make backing safer, the RLX’s cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The Taycan doesn’t offer a cross-path warning system.

Both the RLX and the Taycan have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras and available around view monitors.

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, its standard front crash prevention system, and its headlight’s “Acceptable” rating, the Insurance Institute for Highway Safety grants the RLX the rating of “Top Pick” for 2018, a rating granted to only 153 vehicles tested by the IIHS. The Taycan has not been tested, yet.

Acura’s powertrain warranty covers the RLX 2 years and 20,000 miles longer than Porsche covers the Taycan. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the Taycan ends after only 4 years or 50,000 miles.

There are over 40 percent more Acura dealers than there are Porsche dealers, which makes it easier should you ever need service under the RLX’s warranty.

The RLX’s maximum EPA estimated driving range on a full tank of fuel is 536.5 miles, after which it can be refueled at any gas station in minutes. The Taycan’s range is only 201 miles, after which the minimum recharge time is 22 minutes for only a 80% charge at a specially configured quick charge station not available in most areas. A full recharge at a conventional charging station can take up to 11 hours.

For more complete vehicle control the RLX offers an optional manually controlled automatic, with the available convenience of an automatic transmission and the complete gear control of a manual transmission without the inconvenience of a clutch. A manually controlled automatic allows the driver to eliminate unwanted shifts and maximize engine braking by down shifting while cornering. The Taycan doesn’t offer a transmission that allows complete gear control.

A 10-speed automatic is standard on the Acura RLX, for better acceleration and lower engine speed on the highway. Only a 2-speed automatic is available for the Taycan.

The RLX offers a standard sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The Taycan doesn’t offer an SMG or a conventional manual transmission.

For better traction, the RLX has larger tires than the Taycan (245/40R19 vs. 225/55R19).

The RLX’s tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the Taycan 4S’ standard 55 series front and 45 series rear tires.

The Acura RLX may be more efficient, handle and accelerate better because it weighs about 750 to 800 pounds less than the Porsche Taycan.

For excellent aerodynamics, the RLX has standard flush composite headlights. The Taycan has recessed headlights that spoil its aerodynamic shape and create extra drag.

The RLX uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The Taycan doesn’t offer active noise cancellation.

Because it has more passenger and cargo room, the EPA rates the RLX a Mid-size car, while the Taycan is rated a Compact.

The RLX has 14.1 cubic feet more passenger volume than the Taycan (102.1 vs. 88).

The RLX has .5 inches more front legroom, 3.2 inches more front shoulder room, .1 inches more rear headroom, 6.6 inches more rear legroom and 3.8 inches more rear shoulder room than the Taycan.
