The Lexus IS 250C SE-L stands out as a premium hardtop convertible that prioritizes refinement, reliability, and everyday usability. Produced between 2009 and 2015, this four-seat drop-top combines the elegance of a coupe with the freedom of open-air motoring, powered by a responsive 2.5-liter V6 engine.
Design and Build Excellence
Crafted with Lexus’s renowned attention to detail, the IS 250C SE-L features a sleek exterior that balances sporty lines with sophisticated styling. Its fully automatic folding hardtop retracts in about 20 seconds, transforming seamlessly from a rigid coupe to an open convertible while maintaining structural integrity. The body benefits from extensive reinforcement, adding around 100kg to the saloon’s weight at 1,730kg, which minimizes scuttle shake and chassis flex for a solid feel even over rough roads.
Inside, the cabin exudes luxury with high-quality materials, supportive leather seats, and ample space for four adults. Rear passengers enjoy surprising legroom for a convertible, making it a genuine family-friendly option with the roof up. Boot space remains practical at around 350 liters with the top down, outperforming many rivals.
Powertrain and Driving Dynamics
At the heart of the IS 250C SE-L is a 2.5-liter V6 engine delivering 204-208 horsepower and 185-252 Nm of torque, paired exclusively with a six-speed automatic transmission featuring manual shift mode. Acceleration from 0-62 mph takes approximately 8.4-9.0 seconds, providing adequate performance for relaxed cruising rather than track-day thrills.
Handling is composed and predictable, with steering that offers genuine feedback without being overly heavy. The ride, especially on optional 18-inch wheels, leans firm to preserve chassis rigidity, though it absorbs bumps tolerably well. Rear-wheel drive enhances balance, making it engaging on winding roads while prioritizing comfort over outright sportiness.
| Performance Metric | IS 250C SE-L | Key Notes |
|---|---|---|
| 0-62 mph | 9.0 seconds | Smooth but not explosive |
| Top Speed | ~140 mph | Limited by electronics |
| Engine | 2.5L V6, 204 hp | Refined power delivery |
| Transmission | 6-speed Auto | Paddle-shift capable |
Fuel Efficiency and Running Costs
Official combined economy hovers around 30-31 mpg, with CO2 emissions at 213 g/km. Real-world figures from owners average 29-36 mpg, often exceeding 104% of lab-tested values thanks to the engine’s efficiency in mixed driving. However, spirited open-top runs can drop this to under 20 mpg, and it’s less frugal than diesel rivals like the BMW 325i at 37 mpg.
Originally priced from £41,231 for the SE-L, used examples now offer strong value, bolstered by Lexus’s legendary reliability. Maintenance costs are reasonable, with few reported issues beyond standard wear.
- Average Real MPG: 29-36 mpg based on owner reports
- Official MPG: 30.7 mpg combined
- CO2: 213 g/km, impacting road tax
- Fuel Type: Premium unleaded recommended
Interior Comfort and Technology
The SE-L trim elevates luxury with features like heated seats, dual-zone climate control, and a premium audio system—options like the Mark Levinson 12-speaker setup deliver exceptional clarity. Refinement shines through low wind noise, even at highway speeds with the top down, and a quiet cabin surpassing class competitors.
Practical touches include a usable rear seat and generous trunk space. Safety is comprehensive, with active systems like radar cruise control and pre-collision warning available on higher specs, alongside standard airbags and stability controls.
Reliability and Ownership Experience
Lexus owners praise the IS 250C for its bulletproof build, with many reporting trouble-free ownership. Common positives include smooth operation, comfort, and retained value. Minor gripes involve the firm ride and modest performance, but it’s far superior to wobblier convertibles like the Saab 9-3.
“Nicely built and impressively reliable, the IS 250C is well equipped, decently refined and pretty practical.”
It’s an ideal choice for those seeking a dependable luxury drop-top without the premium price of BMW or Mercedes equivalents.
Comparing to Rivals
| Model | Power (hp) | 0-62 mph | MPG (Combined) | Price (New) |
