The Aurora's influence on the Alero appears to carry through to the interior as well. Like the Aurora, the Alero interior is a solid design. Everything seems natural and sensible without being ordinary or boring, a difficult combination to master these days. Instruments are large and legible, located under a deep, curved hood. Audio controls are positioned in the center of the dash above the climate controls, where they belong. The climate control layout uses rotary switches, a familiar design that is elegant and easy to use.
Interior colors, textures, and shapes reinforce our feeling that Oldsmobile's design team benchmarked every Japanese car in the segment as well as some of the domestic competition. It looks rich and expensive inside the Alero and fitment of the pieces was remarkable in the GLS Sedan we drove.
Blocky in design, the Alero's seats look similar to those found in many GM vehicles, but they provide good support when cornering. Interior space is comparable to other cars in this class and my 6-foot, 4-inch frame was comfortably ensconced. We especially liked the seat-mounted three-point seat belts, which move fore and aft with the seat; they seem more comfortable around the shoulder than traditional belts mounted to the door frames.
We were surprised and delighted that the Alero was so much fun to drive. Everything we hated about the Achieva's weak powertrain and mediocre chassis has been banished from the Alero.
The Alero GLS offers more grip than we would have expected from Oldsmobile's high-end, high-volume family car. Some of this comes from the GLS model's larger P225/50R-16 Goodyear Eagle LS Touring tires mounted on wider alloy wheels. At the same time, there is little harshness or vibration transmitted through to the passengers. The larger tires impart a somewhat heavier feel to the steering. But the steering is responsive and makes the driver feel better connected to the road. Like most cars from GM, there's a slight dead spot at straight-ahead, but overall the package is nicely balanced.
The ride quality is smooth and much more controlled than the Achieva. The Alero feels taut, yet there's a noticeable absence of shimmy and shake and rattles over potholes. Front and rear suspensions comprise MacPherson struts attached to the car with intermediate subframes. This design allows the springs to keep the tires in good contact with the road without transmitting a lot of harshness to occupants. Oldsmobile engineers designed an ultra-stiff floor pan and a compliant suspension with increased travel that provides a level of quietness and smoothness that the Achieva never had. Bushings, springs, strut damping, and front and rear anti-roll bars were all developed to provide the ride and handling performance demanded by import-oriented customers.
The 3.4-liter V6 that came on our GLS is a lineal descendant of the 2.8-liter V6 introduced in 1980. It was later increased to 3.1 liters and then 3.4 liters of displacement. Along the way, it was blessed with hundreds of mechanical and system improvements. It may not be a fire-breather, but it produces more power than most of its competitors.
We also spent some time with the standard 2.4-liter engine. With its relatively flat torque curve, this engine delivers plenty of power around town and offers good acceleration for tackling freeway on-ramps. The four-speed automatic offers smooth, positive shifts and seems a good match for the engine.
The four-speed automatic is the same transmission found in the Oldsmobile Silhouette minivan, but has been recalibrated for quicker downshifting-a welcome improvement.
All Aleros come standard with anti-lock brakes and electronic traction control. Aluminum brake calipers are 20-percent lighter than cast-iron designs; decreasing this unsprung weight reduces oscillations of the wheel over bumps for better handling and a more controlled ride. The traction control system uses ABS wheel-speed sensors that detect when the front wheels are spinning; torque is reduced by upshifting the transmission, retarding ignition timing and, if necessary, cutting fuel to the injectors. Oldsmobile says this system has proven to be more effective than traction control systems that use both power reduction and brake application to maintain control. A switch allows the driver to turn the system off when needed.
