Lexus IS F Model Year Overview

Detailed Explanations

2008: Launch Year; First Production Run; Aggressive Tuning

The 2008 IS F was the first of its kind, boasting a potent 5.0-liter V8 engine producing 416 horsepower. This model year is characterized by its aggressive engine and transmission tuning, offering a raw and engaging driving experience. However, being the first production year, it's essential to thoroughly inspect the car for any potential issues stemming from early manufacturing processes.

2009: Revised Transmission Tuning; Improved Fuel Delivery

Lexus addressed some initial concerns with the 2009 model year, primarily focusing on refining the transmission tuning for smoother and more predictable shifts. They also made improvements to fuel delivery, aiming to mitigate the reported fuel smell issue. While the fuel smell wasn't entirely eliminated, it was significantly reduced compared to the 2008 models.

2010: Revised Steering ECU; Minor Interior Updates

The 2010 IS F received updates to the steering ECU, aiming to improve steering feel and responsiveness. Minor interior updates were also implemented, although these were largely cosmetic and didn't significantly alter the overall driving experience. This model year is generally considered a solid choice, offering a balance of performance and refinement.

2011: Suspension Upgrades; Torsen Limited-Slip Differential Added; New Interior Trim

The 2011 model year marked a significant upgrade for the IS F. Lexus implemented suspension upgrades, enhancing handling and ride quality. More importantly, a Torsen limited-slip differential (LSD) was added, dramatically improving traction and cornering performance. New interior trim options were also introduced, adding a touch of sophistication to the cabin. The addition of the LSD makes the 2011 and later models highly desirable.

2012: No Major Mechanical Changes; Minor Cosmetic Updates

The 2012 IS F saw no major mechanical changes from the 2011 model. The updates were primarily cosmetic, focusing on minor styling tweaks and interior enhancements. This model year offers a similar driving experience to the 2011, with the added benefit of potentially being newer and having lower mileage.

2013: Last Production Year; No Major Changes

The 2013 IS F represents the final year of production for this iconic model. No significant changes were made compared to the 2012 model. Being the last year, these models are often sought after by collectors and enthusiasts, potentially commanding a higher price.

2014 (Limited Availability)

While the IS F was officially discontinued in 2013, some regions may have received a limited number of 2014 models. These are essentially 2013 models registered as 2014 vehicles. If you encounter a 2014 IS F, carefully verify its production date to confirm its authenticity and avoid potential misrepresentation.

Fuel Smell Issue

The fuel smell issue, primarily affecting 2008 and to a lesser extent 2009 models, is a common concern among IS F owners. The smell is often noticed after refueling or during hot weather. While Lexus attempted to address the issue with revised fuel delivery systems in later models, it wasn't entirely eliminated. Potential causes include fuel vapor leaks from the fuel tank or fuel lines. Before purchasing an early model IS F, thoroughly inspect the car for any signs of fuel leaks and be prepared to address this potential issue.

Transmission Programming (2008-2009)

The early IS F models (2008-2009) are known for having more aggressive and sometimes less refined transmission programming compared to later years. This can manifest as abrupt shifts, especially in lower gears. While some owners appreciate the raw and engaging feel, others find it less desirable. Consider test driving both early and later models to determine your preference.

Torsen Limited-Slip Differential (LSD)

The addition of the Torsen LSD in the 2011 and later IS F models is a significant upgrade. The LSD dramatically improves traction and cornering performance, making the car more enjoyable to drive, especially on twisty roads or in track settings. If performance and handling are your priorities, opting for a 2011 or later model is highly recommended.

High Mileage Considerations

Given the age of the IS F, many examples on the market will have accumulated significant mileage. While the 2UR-GSE engine is known for its durability and reliability, high mileage can increase the risk of potential issues. Thoroughly inspect the car's maintenance history, paying close attention to oil changes, fluid flushes, and other preventative maintenance services. Also, consider having a pre-purchase inspection performed by a qualified mechanic to assess the overall condition of the car.

Frequently Asked Questions
