The 2017 Lexus ISF represents the pinnacle of Lexus’s pursuit of driving perfection, a model that arrived relatively late in the IS generation but quickly etched its name into the sport sedan hall of fame. As the high-performance variant of the IS platform, it was never intended to be a volume seller but rather a statement of engineering prowess and a halo car for the division. With its naturally aspirated V8 screaming in the rear and a rear-wheel-drive layout, the ISF offered a raw and engaging experience that stood in stark contrast to the growing trend of turbocharged and hybrid powertrains.
Design and Aerodynamics: Form Meets Function
Visually, the 2017 Lexus ISF commands attention with a stance that is both aggressive and elegant. The design language is more mature and muscular compared to its lesser-equipped siblings, featuring a widened front bumper with large air shutters that actively manage airflow to cool the brakes and engine. A prominent front grille and aggressive side skirts work in concert to channel air efficiently, reducing lift and increasing high-speed stability. The visual impact is completed by 19-inch forged alloy wheels shod in performance tires, a subtle rear lip spoiler, and a dual-exhaust tailpipe that hints at the power lurking beneath the sculpted hood.
Performance Engineering: The Heart of the Machine
At the core of the ISF’s appeal is its meticulously crafted 5.0-liter “2UR-GSE” V8 engine, a piece of art for petrolheads. Producing 416 horsepower and 390 lb-ft of torque, the naturally aspirated unit delivers linear power progression and an intoxicating high-revving character that feels almost analog. The power is sent exclusively to the rear wheels through a tightly calibrated 6-speed automatic transmission with steering-wheel-mounted paddles, ensuring shifts are crisp and responsive. This powertrain combination allows the ISF to sprint from 0 to 60 mph in just over 4 seconds, a figure that remains impressive even by today’s standards.
Handling and Dynamics
Lexus engineered the ISF to handle with precision, making it feel significantly more agile than its full-size luxury competitors. The suspension setup features a Bilstein monotube shock absorber system at the rear and a performance-tuned front suspension, providing a balance of comfort and control. The steering is weighty and communicative, feeding back valuable road information to the driver. For enhanced cornering grip, the ISF came standard with a limited-slip differential, ensuring power is delivered efficiently to the rear wheels during aggressive exits and tight cornering maneuvers.
Interior and Technology
Stepping inside the 2017 ISF reveals a cabin that blends sporty aesthetics with Lexus’s renowned build quality and comfort. The driver-centric cockpit is accentuated by black suede-like Micro Suede upholstery, contrast stitching, and red accents, creating an atmosphere focused on the driving experience. Supportive bucket seats keep the driver securely in place during spirited runs, while still offering plush comfort for daily commutes. The infotainment system features a large touch screen with navigation, Bluetooth connectivity, and a premium Mark Levinson audio system, ensuring the cabin remains technologically current and acoustically refined.
