We drove the Nissan Maxima SV with the Sport package. Like the S model, it comes with a very strong, very responsive 3.5-liter V6 engine uprated from the previous 255 horsepower to 290 horsepower, a 35-horsepower increase with a concomitant gain of nine foot-pounds of torque and a one-mile-per-gallon increase in fuel economy. It has both variable valve timing and a variable intake system, a system that opens wide at about 4,500 rpm, wide enough that you can hear the engine sound change dramatically, adding to the driving enjoyment.

At 290 horsepower, the Maxima's V6 is right at the top of the class in terms of power development for its size, but it's not peaky or cranky because the valve and intake systems keep it optimized for whatever gear and rev range.

We found the engine smooth and quiet, right up to the 6,200 rpm redline, and it delivered plenty of punch throughout the rev range. A very strong, very enjoyable engine to drive, and if you can keep your foot out of it, you can get better mileage than the 26 mpg label. If you keep your foot in it, expect 0-60 mph times of 5.8 seconds.

The only transmission available, much to the chagrin of some critics, is the CVT (continuously variable transmission), a much-improved Nissan innovation. The software offers much quicker and more positive shifting than previous CVTs from Nissan. Maxima's CVT offers a manual mode. We found the transmission a joy to use in either mode. It is perhaps the world's second-best CVT, after Audi's. Nissan says the new CVT software contains more than 700 shifting algorithms to cope with every driving situation in every gear from idle to full-throttle and says the transmission can shift 30 percent faster than a human driver can. In the Sport Drive mode, the shifts were lightning quick, and included a very sporty throttle blip on every downshift.

The chassis and suspension under the new Maxima have been upgraded quite a lot from the previous model, with several new technologies added. The front-drive Maxima has six engine mounts now instead of the usual four, and the engine is mounted lower in the chassis for a lower center of gravity and better handling. The suspension is all new, using premium aluminum components, new shock absorbers, front and rear stabilizer bars, and new, sportier geometry. The front-drive system incorporates a new wrinkle that virtually eliminates torque-steer on full, throttle. We found the Nissan Maxima SV Sport always felt agile, glued to the road, and ready to play, with no hint of harshness in the ride.

The speed-sensitive power rack-and-pinion steering system has been borrowed from the sports car, and it makes the driver feel like he is truly connected, truly part of the steering and driving process, never over-boosted or ropey. The front and rear ABS disc brakes have been upgraded, and the rear brakes are now ventilated, where they were solid on the previous model, for better fade-resistance and braking power under severe conditions.

The only time this Maxima gets sporty and rorty is when the engine intake system switches over into high-flow mode above 4,500 rpm. The rest of the time, the car is very quiet inside, with very little intrusion from the outside world.
