The biggest news for the 2002 Infiniti I35 is the new 3.5-liter V6. This engine brings a dramatic increase in horsepower over last year's 3.0-liter engine. That power comes at lower revs, reaching 260 horsepower at 5800 rpm vs. 227 horsepower at 6400 rpm from last year's engine. Torque, that force that propels you from intersections and helps the car power up hills, has been increased from last year's 217 foot-pounds to this year's 246 foot-pounds. (If you must know, the new engine offers improved head porting, a new two-stage induction system, and new injectors, all for improved response, along with drive-by-wire throttle.) The transmission has been upgraded and there's a gated sport shifter. It's a responsive transmission and the only time we even thought about it was when we marveled at how seamless it was.The new engine makes the I35 very responsive when cruising around time, battling stop-and-go traffic, or accelerating onto a freeway. Punch it and this car takes off like a rocket, quickly going up through the gears to take you well into scofflaw county. It jaunts from 0 to 60 mph in less than 7 seconds; that's quick, more than a second quicker than last year's model, though not quite as quick as Acura's 3.2TL Type-S. Ride and handling are nicely balanced. The I35 rides smoothly in most conditions, though it feels a little bumpy on rough roads. The steering feels about right, light but nicely weighted. The car is stable at high speeds, rock-steady at 90 mph, though it starts feeling lighter than the Gibralter-like Infiniti Q45 in the 110-120 mph range. The suspension is soft enough that it floats a little over high-speed bumps. ABS comes standard, helping the driver maintain steering control in a panic stop. During normal use, the brake pedal has an excellent feel. Slamming on the brakes to test the four-wheel ventilated discs generated little nose dive. Pedal feel remained true following numerous hard braking maneuvers; the brakes performed consistently no matter how much we abused them. Nine hours of driving from Virginia to the southern tip of North Carolina's Outer Banks confirmed this is a dynamically superior car. There were opportunities to challenge the suspension, steering, transmission and brakes, and try as we might we could not get the I35 to complain or misbehave. It remained stable and even-keeled with virtually no body lean, even when driving aggressively through switchback turns. At the same time, there's nothing stiff feeling about the suspension. You can pitch the car into a sharp turn harder than is necessary, and it will turn quickly without any sort of negative feedback. As for the ride, Infiniti is masterful in working with the independent front and multi-link rear. This is a car that you can drive forever and be almost oblivious to the condition of the road surface. Besides driving quickly through turns, we found two other situations where the I35 passed the test with flying colors. Changing lanes on the freeway, back and forth, there was never a hint of wandering. And on bumpy surfaces, in a curve, under braking, again: rock steady-and this is a test that few cars can ace.
