The RC’s optional pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The E-Class Coupe doesn’t offer pre-crash pretensioners.

Both the RC and the E-Class Coupe have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available all wheel drive, blind spot warning systems, rear parking sensors and rear cross-path warning.

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, with its optional front crash prevention system, and its standard headlight’s “Acceptable” rating, the Insurance Institute for Highway Safety grants the RC the rating of “Top Pick” for 2018, a rating granted to only 88 vehicles tested by the IIHS. The E-Class Coupe has not been tested, yet.


Lexus’ powertrain warranty covers the RC 2 years and 20,000 miles longer than Mercedes covers the E-Class Coupe.

Fuel Economy and Range

On the EPA test cycle the RC 350 RWD 8-speed Auto 3.5 V6 (311 HP) gets better fuel mileage than the E 400 Coupe RWD (19 city/28 hwy vs. 20 city/26 hwy).

Suspension and Handling

For better maneuverability, the RC’s turning circle is 3.1 feet tighter than the E-Class Coupe’s (34.2 feet vs. 37.3 feet). The RC AWD’s turning circle is 3.3 feet tighter than the E-Class Coupe 4MATIC’s (34.8 feet vs. 38.1 feet).


The Lexus RC may be more efficient, handle and accelerate better because it weighs about 300 pounds less than the Mercedes E-Class Coupe.

The RC is 5.2 inches shorter than the E-Class Coupe, making the RC easier to handle, maneuver and park in tight spaces.

Passenger Space

The RC has 3.6 inches more front legroom and .5 inches more rear shoulder room than the E-Class Coupe.

Cargo Capacity

The RC has a larger trunk than the E-Class Coupe (10.4 vs. 10 cubic feet).


The RC’s instruments include an oil pressure gauge and a temperature gauge – which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The E-Class Coupe does not have an oil pressure gauge.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The RC offers available headlight washers to keep headlight output high. The E-Class Coupe doesn’t offer headlight washers.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the RC has standard extendable sun visors. The E-Class Coupe doesn’t offer extendable visors.
