IS the Lexus IS250 fast?
A quick read: the IS250 prioritizes balance and refinement over outright speed, so it isn’t considered fast by modern performance standards. Typical 0-60 mph times are in the mid-to-high 7-second range, with an electronic top speed around 130 mph.
The speed of the IS250 varies by year, drivetrain, and transmission. Below is a detailed look at how fast the car is, what factors influence its acceleration, and how it stacks up against its siblings in the Lexus IS lineup.
Performance fundamentals
The following figures reflect common IS250 configurations across years and markets.
- Engine and power: 2.5-liter V6, about 204 horsepower (figures can vary slightly by year and market)
- Transmission: typically a 6-speed automatic; a 6-speed manual was offered in some markets but was rare in the US
- Drivetrain: rear-wheel drive standard, all-wheel drive available
- 0-60 mph: commonly in the mid-to-high 7-second range for automatic RWD versions; roughly 7.5-8.0 seconds depending on configuration
- Top speed: electronically limited to around 130 mph
- Fuel economy: roughly 20-23 mpg city and 28-30 mpg highway with automatic transmission; AWD typically slightly lower
Numbers vary by model year, market, and equipment. Manual transmissions, when present, can alter performance modestly, and AWD versions tend to be a touch slower in a straight line than RWD models.
How it compares to related Lexus models
To gauge speed, it helps to contrast the IS250 with its faster siblings in the same family.
- IS350 (3.5-liter V6): typically 268-306 hp, 0-60 mph in about 5.5-6.0 seconds, noticeably quicker than the IS250
- IS F (5.0-liter V8, higher-performance variant in its era): around 416-467 hp, 0-60 mph in the low 4-second range—an outright speed upgrade
- IS F Sport: a trim that emphasizes handling and styling upgrades; engine output remains similar to the base IS250/IS350 variants, so gains are mostly in chassis dynamics rather than raw acceleration
In real-world terms, the IS250 sits between the more comfortable, refined base model and the significantly faster IS350/IS F. It suits everyday driving and highway cruising well, but it isn’t a sport-sedan in the strictest sense when stacked against its higher-performance siblings or modern rivals.
Real-world driving impressions
Owners typically emphasize that the IS250 delivers a smooth, quiet ride and refined power delivery rather than explosive acceleration. The engine is smooth at speed, with adequate mid-range torque for overtakes, but it can feel stressed on steep hills or when fully loaded. The automatic transmission prioritizes smooth shifts over sharp, punchy responses, which colors the perception of speed during daily commuting.
Throttle response and transmission behavior
Throttle response is tuned for calm all-around performance. In most driving scenarios, the IS250 feels composed and effortless, though not particularly quick off the line. The automatic’s shift timing favors comfort, which some drivers appreciate, while others seeking immediate sprint might wish for a more aggressive tuning or a different powertrain.
Should you buy it if speed is a priority?
If speed is your primary criterion, the IS250 isn’t the best option. For quicker acceleration, consider the IS350 or the higher-performance IS F variants, or look at newer compact luxury sedans that offer turbocharged engines or more horsepower. If you value a serene ride, proven reliability, and efficient highway cruising, the IS250 remains a solid choice within its era.
Summary
The Lexus IS250 offers a balanced blend of comfort, refinement, and reasonable everyday performance rather than raw speed. Its 2.5-liter V6 delivers adequate acceleration for typical driving, but it’s visibly outpaced by more powerful Lexus siblings and many modern rivals. For speed enthusiasts, the IS250 is best viewed as a well-rounded sedan with smooth power delivery, not a weapon on the performance front.
Notes on variations
Performance figures vary by year, market, transmission, and drivetrain. If you’re shopping, verify the exact specifications for the specific car you’re considering, especially regarding manual availability, AWD, and factory tuning.
