From Infiniti press: With its award winning 255-horsepower 3.5-liter V6, elegant styling, standard 17-inch wheels and tires, available Vehicle Dynamic Control (VDC) stability system and luxurious interior appointments, the Infiniti I35 made a major impact on the mid-size luxury class when it was introduced as a 2002 model. For its sophomore season, the I35 continues to offer an unmatched combination of refined luxury and performance with enhancements ranging from expanded wood tone trim on the center console to satellite radio compatibility.
Under the elegant I35 skin beats the heart of a refined performance sedan, starting with its 3.5-liter DOHC 24-valve V6 producing 255 horsepower and 246 lb-ft of torque. The 3.5-liter V6 is part of the VQ engine series that has won acclaim as one of the “Ten Best Engines” from Ward’s Auto World magazine for nine consecutive years. The engine’s advanced design includes continuous variable timing control, a silent timing chain and electronically controlled throttle.
The engine also features microfinished crank journals and cam lobes, molybdenum coated lightweight pistons, Nissan Variable Induction System (NVIS), digital knock control, six individual coils (one per spark plug) and double platinum-tipped spark plugs with a 100,000 mile tune-up interval. An equal-length tuned exhaust with a variable capacity muffler enhances power production and gives I35 a quiet, yet throaty, sound.
Standard on all 2003 I35s is a smooth 4-speed electronically controlled automatic transmission. Every I35 also features standard Traction Control System (TCS), which aids traction in off-the-line starts and slippery road surface situations.
I35 provides a balance of ride and handling with a strut and coil spring front and rear Multi-Link Beam™ suspension, which minimizes camber changes during cornering. Large diameter front and rear stabilizer bars and speed-sensitive power rack-and-pinion steering help give I35 a smooth, controllable ride. A higher level of handling and stability is available with the sport-tuned suspension on Sport Package-equipped I35s.
