How fast IS the IS500?
The IS500 accelerates with a muscular V8 and rear‑wheel drive, delivering 0–60 mph in about 4.4 seconds and a top speed around 168 mph. It uses a 5.0-liter V8 paired with an 8‑speed automatic transmission to channel 472 horsepower to the back wheels.
Here’s a detailed look at the speed-focused specifics of Lexus’ IS500, how those numbers translate to real‑world driving, and how it stacks up against rivals in the luxury sport sedan segment.
Powertrain and performance numbers
The following snapshot highlights the core speed-related specs you’ll want to know about the IS500.
- Engine: 5.0-liter naturally aspirated V8
- Power: 472 horsepower (351 kW)
- Torque: 395 lb-ft (536 Nm)
- Transmission: 8-speed automatic with paddle shifters
- Drive configuration: Rear-wheel drive standard (no factory AWD option)
- 0–60 mph: approximately 4.4 seconds (with RWD)
- Top speed: governed at about 168 mph (270 km/h)
These figures underscore the IS500’s role as a capable, high‑performance variant within the IS lineup, emphasizing straight‑line speed and a sonorous V8 note rather than all‑out cornering prowess alone.
Driving dynamics and real‑world performance
Numbers are meaningful, but how the IS500 feels behind the wheel matters too. The following points summarize what drivers typically experience in everyday and spirited driving conditions.
- Power delivery: Torque is broad, with strong mid‑range shove that helps brisk acceleration in everyday driving and highway passes.
- Transmission tuning: The 8‑speed automatic is designed for quick, seamless shifts with responsive kickdowns when you stomp on the throttle.
- Driving setup: Rear‑wheel drive, balanced chassis, and a firmer ride tuned for a more connected feel—especially with proper tires—compared with softer, comfort‑focused rivals.
In practice, the IS500 offers a thrilling V8 experience with confident straight‑line performance, matched by a soundtrack that appeals to enthusiasts. However, as a luxury sedan, it prioritizes refinement and daily usability alongside speed, and tire choice or weather can noticeably affect traction and acceleration in less than ideal conditions.
Comparisons and context within the segment
Against key rivals and within its own lineup, the IS500’s speed credentials stand out in several ways, while also highlighting trade‑offs common to a V8‑powered luxury sedan.
- Vs. non‑V8 IS models: The IS500 is substantially faster, thanks to the 472 hp V8, while the IS300/IS350 offer less power and different character.
- Vs. all‑wheel‑drive rivals: In markets where AWD variants exist (e.g., some Audi/BMW competitors), the IS500’s RWD setup can feel more playful but may demand more care in low‑traction conditions.
- Vs. turbo‑charged peers: The IS500’s naturally aspirated V8 delivers a unique, high‑revving soundtrack and a linear power curve, contrasting with turbocharged engines that often pull harder at lower RPM but may taper off above peak boost.
Overall, the IS500’s speed profile places it among the quicker luxury sport sedans with a traditional V8 ethos, offering crisp acceleration, a distinctive exhaust note, and a more traditional driving experience compared with some turbocharged competition.
Summary
The IS500 is built for fast, confident performance with a focus on that V8‑powered, rear‑drive experience. With a 0–60 time around 4.4 seconds and a top speed near 168 mph, it sits firmly in the upper tier of its class for straight‑line speed while delivering refined daily usability and Lexus’s characteristic luxury and reliability.
In short, if panoramic speed with a classic V8 soundtrack is your priority in a luxury sedan, the IS500 answers decisively while still offering everyday comfort and Lexus refinement.
