No other gas-powered luxury sedan delivers efficiency this impressive
Luxury sedans traditionally force buyers to choose between comfort, performance and fuel efficiency. Most offer refinement and power, but efficiency usually takes a back seat, especially in gasoline models. That’s why this luxury sedan stands out. It achieves fuel economy figures that rival some entry-level hybrids, while retaining the smooth ride, premium materials and quiet cabin that buyers have come to expect from the segment. For drivers who want luxury without gassing up, it’s in a class of its own.
What makes this efficiency so impressive is that it doesn’t make any major compromises. The powertrain is tuned for real-world driving, delivering performance and relaxed highway cruising rather than chasing claimed power figures. Combined with smart engineering and aerodynamic design, this allows this sedan to stretch every gallon further than any other gas-powered luxury rival currently on sale.
In this article, we explain how this luxury sedan achieves such remarkable efficiency, what it means for long-term ownership costs, and why it challenges the assumption that hybrids are the only path to fuel savings. It’s proof that traditional powertrains can still deliver remarkable results when used well.
To provide you with the most current and accurate information possible, the data used to compile this article comes from various manufacturers’ websites and other authoritative sources, including the EPA.

Combining comfort, performance and high-end features at logical prices.
Acura Integra is the most efficient gas-powered luxury sedan in 2025
If you’re looking for something luxurious and efficient, but you’re not yet ready to upgrade to a hybrid engine, there are few options that actually save you money at the pump. It’s no surprise that it’s a small Japanese sedan that edges out its competitors in this department. Acura’s Integra takes the prize as the most efficient new luxury sedan on the market that doesn’t use electrification.

Acura edges out all its major rivals by offering 32 miles per gallon in its most efficient form. The EPA estimates you’ll save $1,250 on gas over five years by driving this Integra compared to the average new car. Opting for the manual transmission significantly reduces efficiency. If efficiency is one of your main goals, we’d avoid the high-octane Type S model.
It’s worth noting that while the Integra is the most efficient luxury sedan on the market, some rivals come close. The Mercedes-Benz C-Class, for example, manages 29 miles per gallon combined. Even closer is the BMW 2 Series Gran Coupe, which gets 31 miles per gallon.

In addition to being the most effective, it is also the most affordable.
Not only will this Japanese sedan save you extra money at the pump, but it’s also the most affordable option in its class. It undercuts almost all of its competitors by thousands of dollars. Despite this, we think it’s exceptionally well equipped and offers a truly luxurious experience inside.

The luxury subcompact segment may be smaller than most, but there are some pretty powerful players here. The Audi A3, Cadillac CT4, Mercedes-Benz CLA and BMW 2 Series Gran Coupe offer good competition. However, all of these start thousands of dollars more expensive than the little Integra.
If you’re looking for the best value for money, we’ll take a look at the A-Spec version with technology. While this may reduce efficiency a bit, we believe this car was designed to be driven with a manual transmission. It also comes with a sportier aesthetic and a few extra features. We wouldn’t blame you for being wowed by the fantastic Type S either.

This small Japanese luxury sedan is as fun as it is efficient
While the Integra may not be as quick as some of its main rivals, it has a lot to offer in the fun department. It’s based on the Honda Civic, pulling many parts from the fantastic Civic Si. If you think the efficiency losses are worth the extra performance, the Type S is essentially a more comfortable version of the Civic Type R.

Most Integras come with the 1.5-liter turbo-four taken from the Honda Civic Si. A CVT is your only option on base and A-Spec models. The A-Spec with Technology, however, can be equipped with a sleek six-speed manual transmission. The Type S draws its engine from the Honda Civic Type R, along with a number of other performance parts. This model comes exclusively with a manual transmission. Every 2026 Integra is front-wheel drive.
Acura’s small sedan may not be as quick as some of its rivals, but its lively chassis is the star of the show. The Integra always feels like it wants to be pushed to the extreme. The CVT dulls the fun a bit, which is why we’d switch to the manual. Manual models also benefit from a limited-slip differential and a rev-match system.
The Type S takes things up more than a few notches. It features a larger, more powerful engine as well as a number of other improvements. Although the Civic Type R is undoubtedly the more capable machine, the Acura offers a better balance between track days and daily driving.
