Sunfire's awesome foursome includes the SE Coupe (Base Price (MSRP) $12,995), SE Sedan ($12,995), SE Convertible ($19,995), and GT Coupe ($15,995).The coupes and the convertible offer the most excitement, but the SE Sedan provides more practicality with a roomier back seat and a larger trunk.
With a moderately raked windshield, Sunfire's coupes offer a surprisingly large greenhouse, with generous glass area and few obstructions to outward visibility. At the rear, a relatively short deck lid conceals slightly more than 12 cubic feet of trunk space, easily accessed with a low lift-over height.
A rear decklid spoiler is now standard on all 1998 Sunfire coupes. Though it wasn't available on early production models, Sunfire sedans will also sport a new decklid spoiler with an integrated center brake light.
The Sunfire Convertible resembles a miniature Firebird with its fluid curves, sharp, tapered nose, muscular bodyside bulges and stocky tail treatment. Pontiac's Sunfire looks sportier than Chevy's Cavalier. Because they share platforms, powertrains and trim levels, these two models offer similar dynamic traits.
Under the hood, Pontiac provides the choice of two powerplants and three transmissions.
Standard in the SE coupe, sedan and convertible is a 2.2-liter overhead-valve inline 4-cylinder engine that generates 115 horsepower and 135 pound-feet of torque. A Sunfire with the 2.2-liter engine and standard five-speed transmission gets an EPA-rated 23 mpg in the city and 33 mph on the highway.
To improve acceleration performance off the line, Pontiac has redesigned the 2.2-liter engine. Changes in the combustion chamber design, a new composite intake manifold, roller rocker arms and a new aluminum cylinder head design, have increased torque from 130 pound-feet at 4000 rpm to 135 pound-feet at 3600 rpm. Horsepower rating for the 2.2-liter engine is 115 at 5000 rpm, down from previous engine of 120 hp at 5200 rpm. Pontiac hopes the improved launch characteristics of the car will help attract younger buyers.
A more powerful 2.4-liter Twin Cam engine pumping 150 horsepower and 155 pound-feet of torque comes on the Sunfire GT Coupe.
Transmission choices include a 5-speed manual, a 3-speed automatic and a 4-speed automatic. The 5-speed gearbox is precise and fun to use, and a big improvement over the previous manual transmission. The fun factor of the 5-speed manual kicks up a notch with shift linkage improvements that ensure a more precise shift feel.
The 4-speed automatic is available for all models and offers much better gearing than the base 3-speed automatic.
A traction control system is available, but only with the four-speed automatic. Traction control reduces engine power when one of the front wheels begins to spin.
An electronically controlled capacity clutch is now standard on the 4-speed automatic. Transmission improvements complement the 2.2-liter engine for the better launch feel.
Standard on the GT Coupe are P205/55 performance tires on 16-inch aluminum alloy wheels.
The PASSlock theft deterrent system, equipped on all Sunfire models for 1998, shuts the Sunfire off after a few moments if the car is started with anything other than the encoded key. A single key is used for ignition and all locks, and a remote keyless entry system is available as an option.
All Sunfires are equipped with daytime running lights. Whenever the ignition is on and the handbrake is released or the automatic transmission is shifted out of park, the headlights will be on at reduced power. The normal headlights can be switched on manually or by using Pontiac's Twilight Sentinel system, turning the lights on and off automatically as it senses the amount of available light.
