The Lexus NX 450h+ is the top performer in the luxury vehicle sector when it comes to fuel efficiency, but Lexus makes a few other options with excellent gas mileage as well. 
Lexus is a best-selling luxury vehicle brand for a reason, having earned a solid reputation for reliability, longevity, and quality. As fuel costs increase, though, drivers are seeking out more than just luxury—they need fuel efficiency, too.

Which Lexus models have the best gas mileage?

For next-level gas mileage, the best Lexus models to look at are the Lexus NX 450h Plus plug-in hybrid SUV, the
Lexus ES 300h
hybrid sedan, and the
Lexus UX 250h
hybrid subcompact SUV: 
  • Lexus NX 450h+: up to 84 MPGe combined
  • Lexus ES 300h: up to 44 mpg combined
  • Lexus UX 250h: up to 42 mpg combined 
That doesn’t tell the whole story, though…and not everyone wants a hybrid! Whether you’re on the hunt for the absolute most efficient vehicle or a gas-powered car with the best fuel economy, you have plenty of choices in the Lexus lineup—and outside of it!

The most fuel-efficient Lexus cars

If fuel efficiency is your top priority, there’s no beating the 2022 Lexus NX 450h+. As the brand’s first plug-in hybrid vehicle, the popular NX SUV gets a major boost when it comes to fuel economy. With a 2.5-liter four-cylinder engine paired with an 18.1-kWh lithium-ion battery and two electric motors, the NX 450h+ has an EPA-estimated 36 mpg with gas alone…but it earns 84 combined MPGe when running on electricity and gas. 
The NX 450h+ can get you up to 37 miles on electricity alone, which will save quite a bit of money at the gas pump if you’ve got a relatively short commute. The luxury PHEV starts at $56,150 MSRP, which is around average for the class. (In comparison, the standard hybrid NX models get 39 mpg combined, and gas-powered NX models earn 25 combined mpg.)
In second place is the 2023 Lexus ES 300h hybrid sedan, starting at $43,690. The ES 300his a standard hybrid—not a PHEV—but its 2.5-liter four-cylinder engine will still get you a combined mileage of 44 mpg
When it comes to non-hybrid models, Lexus vehicles aren’t the most fuel-efficient on the market. Coming in at first for gas-powered models is the 2022 Lexus UX200 subcompact crossover, getting 32 mpg combined (29/37 mpg for city/highway) and starting at a modest $34,600. Don’t get too attached though—Lexus is dropping all non-hybrid UX models for 2023. 
Lexus hybrid models are unbeatable when it comes to fuel-efficient non-electric luxury models. In fact, the NX 450h+ is the most efficient vehicle in its class!

Most fuel-efficient Lexus SUVs

The NX 450h+ isn’t only the most fuel-efficient Lexus SUV—it’s the most efficient Lexus in general. If you need something a bit larger than the NX crossover, though, Lexus has a few more fuel-efficient options. 
For other fuel-efficient Lexus SUVs, it’s a tie for second place. The hybrid version of the Lexus UX 250h and the standard hybrid NX engine both earn an EPA-estimated 39 mpg combined. The UX is the smaller option, but it’s also the more budget-friendly with a starting MSRP of $36,425—nearly $6,000 cheaper than the NX 350h’s starting price of $42,125 MSRP.
The only other Lexus SUV that could be considered “fuel efficient” is the RX 450h hybrid crossover, starting at $49,870 with a 30 mpg combined EPA rating. If you need the bonus third row of the extended L model, you’re looking at a price tag closer to $53,260
If you’re looking for a larger Lexus SUV that will help you cut back on fuel costs, you’re out of luck. Neither of the brand’s larger SUV options—the GX or the LX—comes in a hybrid version, which means less-than-stellar fuel efficiency. The LX gets 19 mpg combined while the GX earns just 16 mpg combined
Lexus may be the top dog in the fuel-efficiency race, but there are a few competitors hot on its tail. Here are the best fuel-efficient luxury options on the market:

Most fuel-efficient non-hybrid Lexus models

If you aren’t ready to hop on the hybrid train just yet, Lexus has plenty of gas-powered models to consider. Let’s break it down by body style. 
Lexus offers two different coupe models for drivers with a need for speed…and little need for space. The more approachable
RC
coupe earns a decent 25 mpg combined, getting up to 31 mpg on the highway. The top-level LC coupe, on the other hand, gets just 19 mpg combined. 
The RC isn’t only more fuel-efficient, but its starting $43,545 MSRP price tag will be more budget-efficient than the LC’s $94,125. 
Between the three Lexus sedans, the non-hybrid ES four-door sedan still comes out on top with an EPA-estimated 28 mpg combined with the ES 250 model. With the bigger engine of the
ES 350
, fuel efficiency dips down to 26 mpg. The 2022 ES starts with a $41,875 price tag.
Lexus currently offers five different non-hybrid SUV models. Unsurprisingly, the smallest sibling—the UX earns the best mileage. The 2022 UX 200 model achieves a combined mpg of 32 with a smooth 37 mpg on the highway. The standard UX starts at $34,225 while the F Sport trim has an MSRP of $36,940. 
Lexus beats the competition in almost every category…except for the luxury sedan genre. The distinction of most fuel-efficient non-hybrid luxury sedan goes to the 2022 Audi A3, offering a combined 32 mpgand a lower starting price of $34,800.
