The Lexus IS500 Is Almost Perfect: A Deep Dive Into Lexus’ Last Great V8 Sports Sedan

The Lexus IS500 is one of the most important performance sedans of the modern era. It’s not just another luxury four-door car — it is the final chapter in Lexus’ naturally aspirated V8 legacy, a living reminder of what pure performance feels like before the automotive world becomes dominated by hybrid powertrains and electric torque.

With a roaring 5.0-liter naturally aspirated V8, rear-wheel drive, and a timeless design, the IS500 delivers something no competitor dares to offer anymore: old-school emotion combined with Japanese reliability. In many ways, it is almost perfect — and that’s exactly what this massive, in-depth review is about.

Why the Lexus IS500 Matters in 2025

There are many powerful sports sedans on the market, but none offer what the IS500 brings:

• A naturally aspirated V8 — increasingly rare
• A focus on smooth power delivery instead of turbo lag
• Legendary Lexus reliability
• A “sleeper” design appeal
• A price point that undercuts German rivals
• Minimal maintenance headaches
• A daily-drivable performance car

Most modern performance sedans use 2.0-liter four-cyl turbo engines or 3.0-liter V6 turbos. They’re fast — but they don’t feel the same. The IS500 is special because it delivers a type of performance that no longer exists in its class.

The Legendary 5.0L V8: Heart of the IS500

At the soul of the IS500 lies Lexus’ iconic 2UR-GSE 5.0-liter V8, the same engine found in:

• Lexus RC F
• Lexus GS F
• Lexus LC 500
• Previous IS F models

It’s one of the greatest modern V8s ever engineered.

Engine Specs

The Sound

This V8 is not quiet — it’s a symphony. From low-RPM growls to high-RPM screams, the IS500 sounds like a muscle car wearing a tuxedo.

There is no artificial sound enhancement, no turbo hiss, and no electric silence. Just pure mechanical charm.

Real-World Performance: Smooth, Strong, and Emotional

The IS500 delivers performance differently from its turbocharged rivals.

Key Driving Characteristics

• Immediate throttle response
• Linear powerband
• Predictable handling
• No turbo lag
• Strong mid-range power
• Brakes built for repeated spirited driving

While the IS500 isn’t the fastest car in its segment on paper, it offers the best driving feel, which matters more to enthusiasts.

Comparison Table: Lexus IS500 vs BMW M340i vs Audi S4 vs Cadillac CT5-V

Verdict:
The competitors may be quicker or more modern, but none match the IS500’s V8 character, sound, and long-term reliability.

Interior Design: Understated Luxury Done Right

The IS500 interior isn’t futuristic — and that’s a good thing. It feels familiar, comfortable, and extremely well-built.

Interior Highlights

• Real leather seating
• Analog and digital gauge combination
• Clean driver-focused layout
• Mark Levinson premium audio
• Heated & ventilated seats
• Fat, sporty steering wheel
• Precise paddle shifters

Some critics say the interior design is dated, but Lexus fans love its simplicity and timelessness.

Technology: Better Than Expected

While the IS500 doesn’t try to be a tech showcase, it offers all modern essentials:

• Apple CarPlay
• Android Auto
• Large touchscreen
• Backup camera
• Parking sensors
• Adaptive cruise control
• Lane-tracking assist

It’s not as screen-heavy as the BMW M340i or Mercedes C-Class — but that’s part of its charm.

The Driving Experience: The IS500’s True Magic

While many sports sedans focus on raw numbers, the Lexus IS500 focuses on the experience.
This car is engineered for people who love the art of driving — the sound, the throttle response, the rear-wheel balance, and the connection between driver and machine.

The IS500 is not trying to dominate Nürburgring lap times. Instead, it’s built to make your daily commute feel special and your weekend backroad drive unforgettable.

Throttle Response – The Naturally Aspirated Advantage

Turbocharged engines may produce more torque on paper, but nothing compares to the instant response of a naturally aspirated V8.

When you press the accelerator in the IS500, you get:

• No turbo spool delay
• No artificial boost curve
• No “dead zone” at low RPM
• Immediate, predictable power delivery

This makes the IS500 more engaging and satisfying even at low speeds — a trait almost no modern turbo sedan can replicate.

Steering Feel and Precision

The IS500 carries over Lexus’s famous IS chassis balance — something refined over decades.

Steering characteristics:

• Weighty at higher speeds
• Light but precise at city speeds
• Excellent communication through the wheel
• Direct corner-entry confidence
• Minimal play or softness

It does not try to feel overly “digital” or hyper-assisted. Instead, the steering gives honest feedback — something BMW was once famous for but has moved away from.

Suspension Tuning

The IS500 uses Lexus’s Adaptive Variable Suspension (AVS) which automatically adjusts damping based on:

• Road surface
• Steering input
• Acceleration
• Braking
• Driving mode

Ride quality summary:

Lexus struck a perfect balance:
firm enough to feel sporty without becoming harsh or uncomfortable.

Unlike some German competitors, the IS500 never tries to punish you for choosing the performance model.

Handling: Rear-Wheel Drive Done Right

The IS500 is not AWD — and that is part of what makes it special.

What RWD offers the driver:

• Better throttle-based corner rotation
• A more “alive” feeling in turns
• Classic performance sedan dynamics
• No front-axle power interference

On twisty roads, the IS500 feels planted but playful.
You can:

• Tip it into a corner
• Feel the weight transfer
• Use the V8 to power out with authority

It’s not tail-happy like a Dodge Charger Scat Pack — it is refined, predictable, and mature.

Braking Performance

The IS500 uses upgraded brakes over the standard IS models:

• 14-inch front rotors
• 12.7-inch rear rotors
• High-performance calipers
• Fade-resistant compound

Under aggressive driving, brakes remain consistent and trustworthy.

Comfort and Daily Usability

Despite being a V8 sports sedan, the IS500 remains shockingly comfortable.

Seating Comfort

The IS500’s seats strike the perfect balance between:

• Bolstering (to keep you planted)
• Softness (for long drives)
• Adjustability
• Support for all body types

Lexus engineering excels at seat ergonomics, and the IS500 is no exception.

Noise Levels

Interior cabin noise is well-controlled:

• Engine noise is present only when you want it
• Road noise is minimal
• Wind noise is low even at highway speeds

This is a sedan you can quietly cruise in — until you step on the gas.

Rear Seats & Practicality

Rear space is adequate but not class-leading.
However, the IS500 offers:

• A comfortable seating angle
• Good legroom for average adults
• Foldable rear seats
• Decent overall usability

The trunk is spacious enough for daily tasks — groceries, luggage, or weekend road trip gear.

Exterior Design: Aggressive Without Being Flashy

Lexus didn’t try to redesign the IS just for the IS500. Instead, they enhanced it with subtle but meaningful touches.

Key Exterior Elements

• Quad exhaust tips
• Larger hood bulge
• 19-inch Enkei wheels
• F-Sport body trim
• LED headlights and taillights
• Wider fenders

Unlike a BMW M340i or Audi S4, which look nearly identical to non-sport variants, the IS500 proudly shows its performance purpose.

A Balanced Design Philosophy

While Dodge and Cadillac lean into “muscle car aggression,” Lexus maintains Japanese elegance:

• Sharp lines
• Tight panel gaps
• A sculpted silhouette
• Aggressive yet clean front fascia
• A timeless design focus

The IS500 will still look good 10–15 years from now — something many modern designs will struggle with as trends change.
