The trend of naturally aspirated engines is fading in today’s performance car market. With stricter emission regulations and a movement towards turbocharged and electric vehicles, many sports sedans have moved away from larger, high-revving engines. This shift means that the distinctive driving experience once typical of this segment is now increasingly hard to find.
In the current automotive climate, turbocharging has become the norm for most sports sedans. While this technology improves power and fuel efficiency, it often sacrifices the seamless throttle response and consistent power delivery that driving enthusiasts appreciate. This trade-off has redefined performance in this category.
Nonetheless, a select few models remain committed to the classic approach, offering a more tactile driving experience. These rare vehicles favor smooth, naturally aspirated power delivery over the high-boost excitement of forced induction. In a market increasingly focused on efficiency, these cars serve as nostalgic reminders of earlier performance ideals.
The information presented in this article has been carefully gathered from multiple manufacturer websites to ensure accuracy and relevance.
Last Vestige of Natural Aspiration: The Lexus IS 350
The Sole Naturally Aspirated Sports Sedan
As emission standards become ever more stringent, naturally aspirated engines are on the brink of extinction. While some people may not find this trend alarming, car enthusiasts recognize the unique charm of an engine designed to reach its peak revs. Currently, the 2026 Lexus IS 350 stands as the final sports sedan operating without forced induction.
2026 Lexus IS Performance Overview
Specifications
Engine: 3.5-liter V6
Transmission: 8-Speed Automatic
Drivetrain: Rear-Wheel Drive (All-Wheel Drive available)
Horsepower: 311 HP @6600 RPM
Torque: 288 lb.-ft. @4800 RPM
This year, Lexus discontinued both the four-cylinder IS 300 and V-8 IS 500, leaving only the V-6-powered IS 350. While its specifications might not stand out in today’s performance landscape, they are still commendable, allowing it to accelerate from zero to sixty in about 5.6 seconds. Although the IS leans more toward comfort than outright sportiness, it can still deliver an enjoyable drive, especially when revving through its power band—a feeling unique to naturally aspirated engines.
The 2026 Lexus IS 350: Price and Trim Options
Pricing and Features
The IS has traditionally been one of the more affordable luxury sedans. However, with the removal of the four-cylinder option, its entry price has increased. Now starting with the IS 350, it positions itself as a more comprehensive luxury sports sedan.
| Model | Average List Price |
|---|---|
| IS 350 F Sport Design | $46,895 |
| IS 350 F Sport | $51,345 |
| IS 350 F Sport Special Appearance Package | $61,485 |
The current iteration of the IS has been around longer than most competitors, yet its recent updates help maintain its modern appeal. While we suggest opting for the F Sport model—which features a sport-tuned suspension and upgraded interior—those seeking extra performance might also consider the F Sport Handling package.
Modern Touches Inside the 2026 IS 350
Updates Keep the Cabin Fresh
While Lexus has consistently excelled in delivering high-quality interiors, the older design was beginning to feel dated. Recent updates have enhanced the cabin significantly without losing the distinctive character of the IS. Improvements have replaced outdated elements with more modern features.
Interior Space and Comfort
| Front Row Headroom | 38.2 inches |
|---|---|
| Front Row Legroom | 44.8 inches |
| Second Row Headroom | 36.9 inches |
| Second Row Legroom | 32.2 inches |
| Cargo Capacity | 10.8 cubic feet |
While the IS prioritizes front passenger comfort, rear space is somewhat limited, making it less accommodating for adult passengers. Cargo space also reflects this compact design, although suitable for casual use. The most noticeable upgrades are in the dashboard layout, simplifying controls and removing the previous cumbersome touchpad, promoting a cleaner interface.
Infotainment and Technology
A significant improvement is the introduction of a new 12.3-inch touchscreen interface, replacing the older trackpad with a more user-friendly layout. This change allows for enhanced connectivity options, including wireless Apple CarPlay and Android Auto. Additionally, customers can opt for a superior 17-speaker Mark Levinson sound system for an elevated audio experience.
Driving Character: An Old-School Enjoyment
Though the IS hasn’t transitioned to a new generation, substantial improvements keep it competitive. The legacy of the naturally aspirated V-6 resonates with enthusiasts, offering a driving experience that many modern, turbocharged rivals cannot replicate. In an era increasingly dominated by forced induction, the IS maintains its charm, promising a rewarding driving experience.
