The Quest is more fun to drive than most minivans. Its suspension is taut, so it's more responsive than all minivans but the Honda Odyssey. Like the Odyssey, it has relatively little lean in corners and nosedive during braking. The steering is crisp, with just the right amount of feedback to let the driver feel connected to the road. Its high seating position offers good all-around visibility.
The Quest handles well. That not surprising once you realize it shares chassis components with the Nissan Maxima and Murano. Granted, the Quest doesn't handle as well as the Maxima, but it feels more stable in corners than a sport-utility vehicle and it handles better than a Toyota Sienna. It is still a very large vehicle, however, so you don't want to toss it into corners like it's a sports car. Also, its size makes parallel parking and backing out of tight spots a chore.
The Quest's 3.5-liter engine is one of the best V6s on the market. It's essentially the same engine used in the 350Z and Infiniti G35. Tuned for the Quest, it's rated at 235 horsepower. Nissan's variable valve-timing system helps optimize efficiency at a wide range of engine speeds. The torque curve is relatively flat and peaks at 240 pound-feet at 4400 rpm. This provides the driver with responsive performance, whether driving around town or cruising on the freeway. The Quest accelerates onto on-ramps with gusto and the five-speed automatic transmission provides quick, smooth downshifts for respectable passing response. The Quest is one of the faster minivans, but its heft prevents the V6 from being as responsive as it is in Nissan's cars. In addition, the throttle can be a bit sensitive at tip-in, so you need a delicate touch when accelerating from a stop, not a great feature in stop-and-go traffic.
Quest rates an EPA-estimated 18/25 mpg City/Highway. It will run on regular unleaded gasoline. The engine controller dials back the ignition timing when it senses regular gas to protect the engine from damage. As a result, the engine delivers less than peak power, but it is still more than adequate for most daily driving. When you want all the available power, just pump in high-octane premium and the engine happily increases its power output.
The Michelin PAX run-flat system is superb and we highly recommend it. Traditional run-flat tires use super-stiff sidewalls and, as a result, suffer from a hard ride. The Michelin PAX system uses a special wheel and a support ring that prevents the tire from deflating or coming off the rim even if all the air is removed and you are driving at 55 mph. Even with what are essentially 19-inch wheels, PAX-equipped Quests maintain a forgiving ride quality with just the right amount of road feel. Changing a tire or waiting for a tow truck can be dangerous, particularly in high-crime areas or in heavy traffic. With the PAX system the driver can continue driving until the tire is replaced.
