2025 Toyota Prius vs 2026 Lexus IS

Decades ago, few cars were anywhere near as fuel efficient as the Toyota Prius. Today, the 2025 Prius remains the fuel economy champion, but numerous alternatives are close behind. Some even offer more interior room at a lower price. That reality, coupled with the Prius’ cramped interior, limited trunk space, and general weirdness, means hybrid car buyers have options. In response, Toyota adds a new Nightshade trim level with a blacked-out look to the 2025 Prius lineup.

Verdict: The point of the 2025 Toyota Prius is fuel economy, but our Prius Nightshade test car averaged 39.2 mpg, falling significantly short of the EPA estimate of 52 mpg in combined driving. That certainly isn’t superior to roomier hybrid cars from Honda, Hyundai, or from within Toyota’s own lineup.

Lexus refreshed the IS for the 2026 model year, infusing it with the latest digital instrumentation, infotainment, and driver-assistance technologies. It also updated the exterior and interior, re-tuned the steering and suspension, and refined the driving experience. However, the lineup loses the IS 300 with the turbocharged four-cylinder engine and the IS 500 with the thundering 5.0-liter V8, leaving a V6-powered IS 350 with rear-wheel drive (RWD) or all-wheel drive (AWD) as the sole model.

Verdict: The 2026 Lexus IS 350 is enjoyable to drive, exudes quality, and boasts a long-standing reputation for reliability. For those who want a small sports sedan with such characteristics, this is the car.
