Japanese carmakers have long dominated the frugal segment with refined powertrains, linear delivery, and conservative gearbox choices, such as a CVT. There is no dearth of sports cars from the Far East.

The 2025 Lexus ES 250 is powered by a 2.5-liter naturally aspirated four-cylinder engine. This mill is identical to the Toyota Camry, and hence, the frugal nature is also shared. It produces 203 horsepower and 184 pound-feet of torque, sent to the rear wheels via an eight-speed automatic transmission. The conservative and linear tuning of the engine’s performance curve and the automatic gearbox contribute to its fuel economy rating of 24/33/28 MPG in the city/highway/combined.
This is commendable, especially given its standard All-Wheel-Drive system, which ideally consumes more fuel than a Front-Wheel-Drive setup. The average cost to drive the Lexus ES 250 AWD is around $2.70. This luxury sedan can travel up to 455 miles on a tankful, thanks to a sizable 15.9-gallon fuel tank.

The Acura Integra repackages the popular and frugal powertrain and Civic nameplate with a lot more luxury and a refreshing, sharp design. It gets the same engine as the Civic Si, a 1.5-liter turbocharged four-cylinder, producing 200 horsepower and 192 pound-feet of torque. The only difference here is the use of a CVT gearbox instead of the engaging stick-shift on the Honda.
This makes all the difference, with the Acura Integra offering up to 33 MPG combined. The only bummer is that the fuel tank is relatively small compared to those of other luxury sedans in its class. But the 12.4-gallon unit still offers 409 miles of driving range. It costs the Acura Integra $3.02 to do 25 miles.
