“Follow Your Impulse”
1983 was the first model year that Isuzu’s Impulse (known as the Piazza in most other parts of the world) became available in the United States. The first-generation Impulse was built on a variant of the aging rear-drive T-body chassis used by the lowly Chevrolet Chevette but was definitely aimed at a notably different market.
The Impulse came much better equipped than a Chevette: standard mechanical equipment for the $9,998 base price (about $23,700 in 2014 dollars) included alloy wheels and four-wheel disc brakes. Inside, power steering, power windows, power door locks, cruise control, air conditioning, tinted glass, a tilt steering wheel, and an AM/FM stereo radio were all included. Optional equipment was spare, with only an improved stereo and turbine wheels available.
For 1983, power for the 2,700-pound Impulse was provided by a 90 bhp 1.9 liter SOHC inline four with multi-point fuel injection (the turbocharged engine did not become available until 1985). Transmissions available were a standard five-speed manual and an optional four-speed automatic. Fuel economy with the manual transmission was 22 city/28 highway by the standards of the day (19/26 by 2014 standards). 0-60 took around 11 to 12 seconds, with a top speed of about 100 mph.
Of course, the Impulse’s absolute killer feature was its exterior styling, which was very close to Giorgetto Giugiaro’s 1979 “Ace Of Clubs” show car.
Isuzu gets real credit for messing as little as possible with Giugiaro’s excellent and differentiating design—few automakers were willing to leave as well enough alone as they did. They only did a few things, adding slightly larger bumpers to meet the five mph DOT requirement, shortening the windshield and lengthening the hood to allow for easier installation of the engine on the assembly line, and enlarging the overall dimensions a few inches to allow for more interior space.
