The 2017 Lexus IS300 represents the pinnacle of sporty luxury sedans from Toyota’s luxury division, pairing a refined V6 engine with a focus on engaging driving dynamics. This model year marked a significant shift, moving to a rear-drive platform that emphasized balance and precision. At the heart of this performance-oriented machine lies the robust 3.5-liter 2GR-FE V6, a powerplant known for its reliability and smooth delivery of 306 horsepower. Owners and enthusiasts alike seek information on the nuances of this powertrain, from its engineering to its real-world performance.
Engineering the 2GR-FE Powerplant
The 2017 IS300’s 3.5-liter V6 is not just about brute force; it’s a masterclass in smoothness and efficiency for its class. This dual overhead cam engine features VVT-i (Variable Valve Timing with intelligence) on both the intake and exhaust cams, allowing for optimal valve timing under various driving conditions. The result is a power band that delivers strong mid-range torque, making the car feel responsive during everyday driving and confident when merging onto highways. The aluminum construction helps keep the curb weight in check, contributing directly to the vehicle's excellent power-to-weight ratio.
Performance Metrics and Driving Dynamics
Delivering 306 horsepower and 267 lb-ft of torque, the 2017 IS300 provides more than enough thrust for confident highway merging and passing. The power is transmitted through a smooth 6-speed automatic transmission, which features a manual shift mode and paddle shifters for driver involvement. The rear-wheel-drive layout, combined with the well-balanced weight distribution, creates a planted and stable feel through corners. This combination transforms the IS300 from a comfortable cruiser into a compelling driver’s car that reacts predictably to steering input.
Fuel Economy and Real-World Efficiency
Despite its powerful nature, the 2017 Lexus IS300 manages to be relatively frugal, especially when compared to its German rivals. EPA estimates place the fuel economy at 19 city / 28 highway MPG, which is competitive for a mid-size luxury sport sedan. In real-world driving, owners often report figures in the low 20s on the highway, thanks to the efficient Atkinson cycle design of the engine and the vehicle's low drag coefficient. This efficiency ensures that the excitement of driving the IS300 doesn't come with an exorbitant fuel budget.
Reliability and Long-Term Ownership
Lexus has built a reputation for building vehicles that last well beyond 200,000 miles, and the 2017 IS300 is no exception. The 2GR-FE engine is one of the most dependable units in its class, with a proven track record of longevity when maintained properly. Regular oil changes, using the correct 0W-20 synthetic oil, and adhering to the factory maintenance schedule are key to ensuring the turbocharged (in other trims) or naturally aspirated engine runs smoothly for years. This reliability translates into a high resale value and low cost of ownership over time.
Trim Levels and Performance Variants
While the base IS 300h shares the name, it utilizes a different hybrid powertrain. For the 2017 model year, the performance-focused F-Sport trim was a standout option for those seeking a more aggressive stance. The F-Sport package included a sport-tuned suspension, unique aerodynamic enhancements, and larger brakes, all designed to enhance the handling prowess of the already dynamic chassis. Inside, the F-Sport variant distinguished itself with red stitching, bucket seats, and a more aggressive steering feel, catering to the driver who wants every journey to feel special.
