Infiniti I30

From Infiniti press: The Infiniti I30 maintains its segment leadership with evolutionary changes for the 2001 model year, making a great car even better. Two new exterior colors, steering wheel-mounted audio controls and a new rear view mirror with integrated digital compass add the finishing touches to an already outstanding vehicle.

Infiniti introduced the second generation of its popular mid-size luxury sedan for the 2000 model year with all-new interior and exterior styling, more luxury, more interior room, refined ride and handling, and a 37-horsepower increase to its award-winning 3.0-liter V6 engine. Two I30 models are available, the I30 Luxury model and the performance-enhanced I30 Touring model (I30t).

All 2001 I30 luxury sedans feature a 227-horsepower 3.0-liter DOHC V6 with 217 ft-lbs of torque and are backed by a 4-speed electronically controlled automatic transmission. The previous generation I30 had 190 horsepower and 205 ft-lbs., from an engine with the same displacement and layout.

The 37 horsepower/12 ft-lbs increase was realized through use of revised intake and exhaust manifolds with a larger air intake chamber, Nissan Variable Induction System (NVIS) air intake control, equal length exhaust pipes and the addition of a variable capacity muffler adopted from the high performance Nissan Skyline GT-R. A special muffler flap valve, using high temperature aerospace spring technology and materials, opens at 2,000 rpm and above – reducing exhaust system backpressure. These improvements were in addition to the already powerful 24-valve V6, which uses micro-finished crank journals and cam lobes, molybdenum coated pistons, digital knock control, six coils (one per spark plug) and a cross flow coolant pattern. Double-tipped platinum-tip spark plugs offer a 100,000-mile tune-up interval.

All of these improvements add up to the sixth consecutive year of the I30’s innovative powerplant to be named one of the “10 Best Engines” by Ward’s Auto World.

Additional refinements made to the second-generation I30 include a relocated engine control module to increase reliability (located inside the passenger compartment instead of under the hood), a thicker radiator and new cooling fans to keep everything cool and to reduce vibration, a new four-point engine mount design with two electronically controlled fluid mounts.
