For 2018, Lexus IS and RC Model Naming Scheme Is All Kinds of Warped

First things first: Lexus is hardly the only automaker deserving of blame for unintelligibly altering model nomenclature. Moreover, Lexus continues to offer some models for which the badge makes sense. A Lexus LX570, for example, is an LX with a 5.7-liter V8. The Lexus IS350 we tested earlier this month utilizes a 3.5-liter V6.

How sensible. How obvious. How traditional.

But for 2018, the Lexus IS and its RC stablemate will muddy the displacement waters that were already complicated in 2017 by a detuned 3.5-liter V6 that wore IS300 and RC300 badging. In 2018, while the mid-range car continues to make its power from a 260-horsepower 3.5-liter V6 (not the upgraded 311-horsepower 3.5-liter V6 of the IS350 and RC350), the 2.0-liter turbocharged mill that was previously under the hood of the IS200t and RC200t is now the engine under the hood of the rear-wheel-drive IS300 and RC300.

Confused? Yeah, we are, too. Let’s try that again.

Take it from the top.

The 2018 Lexus IS350, both with rear or all-wheel drive, continues with the same 3.5-liter V6 from before, only now with five additional horsepower (for 311 in total).

Down a rung on the ladder you’ll find the 2018 Lexus IS300 AWD. A 260-horsepower version of the 2GR-FKS 3.5-liter V6 is linked to a six-speed automatic.

At the base of the range there’s now a rear-wheel-drive 2018 Lexus IS300. But rather than the 3.0-liter V6 you might expect to find in a model badged as such, and rather than the detuned 3.5-liter V6 of the 2018 IS300 AWD, the rear-wheel-drive 2018 Lexus IS300 is equipped with a 2.0-liter turbocharged four-cylinder producing 241 horsepower and 258 lb-ft of torque, 22 more lb-ft than the IS300 AWD’s 3.5-liter V6.

Carry the same numbers into the RC range and you have it all figured out.

Simple? Straightforward? Transparent? Hardly.

But strategic? Most definitely. Lexus will now badge its entry-level sedan and coupe to appear as though they’re not entry-level cars.

Since Toyota’s upmarket brand was making some designation changes, the larger GS lineup benefited from similar alterations. The GS200t becomes the GS300, albeit still with the same 2.0T. The IS and RC mid-range 3.5-liter V6 does not make an appearance in the GS.

    I've noticed this number discrepancy when I bought my wife a used Lexus Rx400h. It does not have a 4.0L V8 engine as one would guess from the numbering system, but instead has a detuned 3.3L V6 with an electric hybrid motor that when in conjunction mimics the power output of a 4.0L V8. It even makes a angry growl when you get on the throttle. So it appears that Toyota went with a numbering system of comparable power and perhaps their marketing department thought the consumer was not knowledgable enough to know what a 2.0T or 3.3L gas-electric motor would put out. To be fair, a stock 2.0T could range from 145hp - 260hp.

    Not as warped as that front-end bodywork.

      Agreed. Who cares about the nomenclature when the car is so damned ugly?

  • Lorenzo Heh. The major powers, military or economic, set up these regulators for the smaller countries - the big guys do what they want, and always have. Are the Chinese that unaware?
  • Lorenzo The original 4-Runner, by its very name, promised something different in the future. What happened?
  • Lorenzo At my age, excitement is dangerous. one thing to note: the older models being displayed are more stylish than their current versions, and the old Subaru Forester looks more utilitarian than the current version. I thought the annual model change was dead.
  • Lorenzo Well, it was never an off-roader, much less a military vehicle, so let the people with too much money play make believe.
  • EBFlex The best gift would have been a huge bonfire of all the fak mustangs in inventory and shutting down the factory that makes them.Heck, nobody would even have to risk life and limb starting the fire, just park em close together and wait for the super environmentally friendly EV fire to commence.
