If you're shopping for a minivan, you obviously have more interest in utility and function than appearance. Still, with so many good vans to choose from, styling plays an important role, and it's a Previa strong suit.The organic lines are as clean as an egg's, one of nature's perfect containers. The look is futuristic, stopping just short of other-worldly. It's as attractive as any minivan going. And it's a leader in aerodynamic efficiency, reducing wind noise and enhancing fuel economy.
The most unusual feature of the Previa is its powertrain layout. The engine sits in the middle of the van, with the front seats mounted on the leading edge of the engine cover.
This setup has a long history behind it, and it's common to many small Japanese cargo vans sold in Asian markets. Toyota's first U.S. minivan was a direct adaptation of the company's home market van, and it wasn't very successful. The engine ate up lots of interior space, the front seats were almost directly over the front wheels and its handling was awkward.
The current Previa smooths out all those weak points, but the basic concept is the same. With a longer wheelbase than the original van and the engine's mass centered between the wheels, the Previa is well-balanced and provides exceptionally good handling.
Introduced in 1990, the Previa rolled through its first four years with one engine offering: a 2.4-liter 4-cylinder. Like most Toyota engines, it is smooth and durable. But in a minivan, its performance is distinctly deliberate.
Toyota addressed this problem in mid-'94 with a supercharged version of the engine. The advantage of supercharging versus turbocharging is quicker response time and, in this application, a little more power - 161 hp versus the standard engine's 138 hp, 201 pound-feet of torque versus 154 lb.-ft. Torque is a measurement of an engine's ability to do the basic grunt work of motoring - getting the vehicle moving and hauling heavy loads or towing a trailer.
Both engines are bolted to electronicaly controlled 4-speed automatic transmsions.
The Previa is a rear-wheel-drive minivan, another point of distinction from most of its competitors. The Ford Aero-star, Chevrolet Astro/GMC Safari and Mazda MPV are the only others. Rear-drive provides a small edge in dry-weather handling, and is also better for towing.
Front-wheel drive offers traction ad-vantages on slippery surfaces. Toyota's answer to this is a Previa all-wheel-drive option, called All-Trac. It's a sophisticated system, delivering power to the front wheels as needed in low-traction situations, and we recommend it if you live in a region with wet or slippery weather.
Reaching the mid-mounted engine for routine service is a little complicated, but Toyota has addressed this concern by putting the fluid reservoir checkpoints under the hood. Simple, effective and low-hassle.
The Previa is offered in two models: the basic DX and the better-equipped LE. We chose a supercharged LE for our test.
