O Impulse também conhecido por Geo Storm é um modelo de automóvel esportivo compacto fabricado pela Isuzu e vendido nos Estados Unidos por General Motors de 1990 até 1993 como parte da GM Geo linha de automóveis de baixo custo. Os veículos dos mesmos modelos, com pequenas variações, foram vendidos no Canadá a 1992 e 1993. O Storm destinava-se a ser um carro barato com a aparência de um carro esportivo. Pode-se consider ter substituído o relacionado Geo Spectrum, que foi vendido em hatchback e sedan, embora só fosse vendido em hatchback de duas portas e Sedan.

O Geo Storm foi uma versão do esportivo restilado, de segunda geração do Isuzu Impulse com menos algumas das características mais caras do carro. O Impulse Storm foi vendido no Japão como o Nero PA e afins Gemini Coupe. O Storm que faltava ao Impulse Lotus-suspensão, opcional tunada como a do impulse turbo e sistema de transmissão tração total. Although they were essentially the same car, sales of the Storm were much stronger than those of the Impulse—indeed, the Storm sold better than most small GM cars of that era. Slow sales of the Isuzu version doomed the Storm when the Isuzu Impulse was canceled, the Geo Storm derivative had nothing to be built from, meaning both cars were discontinued in 1993. As of 2010, there were only 40,300 Storms registered for road use.

O Storm foi fabricado na planta do Isuzu em Fujisawa, Kanagawa, Japan. O Storm e o Impulse foram vendidos no Canada por GM como o Asüna Sunfire.

A base do modelo SOHC inline-four engine produced 95 hp (71 kW) and had a 9.1:1 compression ratio. The more powerful 1990–1991 GSi used a 1.6L DOHC engine that produced 130 hp (97 kW) and had a 9.8:1 compression ratio. The GSi package also included driving lights, a spoiler, a rear anti-sway bar, and a transmission with a gear ratio that was slightly better for acceleration than the base model's manual transmission.

For 1991 and 1992, customers had the option of purchasing a two-door station wagon body style, also called a wagonback. The base price of the station wagon was $11,450, and it was never offered with the stronger GSi engine. The station wagon was marketed as a "hatchback" and the normal Storm – a more traditional hatchback – was marketed as a "coupé".

In 1992, the Storm was restyled to have a smoother front fascia without the pop-up headlight covers on earlier models. The 1992–93 base models retained the same engine, features, and price that were on the earlier car, with slight interior changes such as different stereos, revised rear speaker locations, and interior trim and upholstery. The GSi version from these years cost considerably more ($13,645–14,560) but this price included a larger 1.8 L 140 hp (104 kW) engine.

The Japanese were also offered the Geo Storm version of the Piazza, called the Piazza PA Nero, which was exclusive to Japanese dealerships called Yanase Co., Ltd. under special arrangement, a dealership that sold GM products in Japan.

Modern sport compacts have faster acceleration and better handling, but the performance figures for the Storm were quite respectable for an economical compact car from that era. Autoweek's 1990 review of the Storm was titled "Slick, Quick And Inexpensive", and described the car as "a good performer" that "handles better than the average new car." When Road & Track compared ten sport compact cars they said the Storm had "the highest skidpad rating (0.85 g), sticks like pine tar to the autocross course, is second-quickest through the slalom and stops shorter from 80 mi ( km/h) than many highly respected sports cars".

Skid pad test figures ranged from 0.81 g to 0.85 g, meeting or exceeding those of the Mazda RX-7 convertible. Sport Compact Car listed the Storm as number three in their "Top Ten of 1992". Hot Rod Magazine's Jeff Smith drove a Geo Storm that was set up for SCCA Super Production racing and declared it to be "every bit as demanding and fun" as racing a Trans-Am series car.

Two different Geo Storm Celebrity Races were held in 1991, the first on July 13 in Des Moines, Iowa, and the second on August 24 in Denver, Colorado. Although they are not the most common type of race cars, modified Storms are still occasionally used to compete in road racing, drag racing and autocross. One of the 2003 entries in the Grassroots Motorsports Challenge was a Storm GSi.

Comentários

Isuzu PA Nero (Japan)

The Storm sold well and was popular with owners, despite getting mixed reviews from automotive magazines. The body styling was "mildly controversial". Kevin Smith of Car and Driver used phrases like "Planet Zarkon" and "space-capsulish" to describe the body, which he listed as one of the best and worst features of the Storm. AutoWeek said that college-aged people tended to "shower the Storm with attention", but that baby boomers tended to "think that at best, the Storm is unusual looking, at worst, odd."

The shape of the body was not the only thing automotive journalists criticized. The engine was described as a "buzzbomb" or "just plain noisy". A few reviewers disliked the suspension, saying the Storm has "above average body lean and needs more rebound control". Some complained about the small cargo area, visibility and the absence of headroom for backseat passengers.

Other aspects of the Storm were more popular with magazine test drivers. Many praised the wide power band of the engine. AutoWeek said, "It revs quickly and easily. Running up to the 7600 rpm redline can be a delight." Automobile Magazine liked the handling, saying, "It's a delight to negotiate twisty...roads with its firm yet compliant suspension."

Year to year changes

• 1991: A "hatchback" (station wagon/wagonback) model was added, other than that, the Storm carried on unchanged.
• 1992: All three models of the Storm received a new headlight cluster (with narrow sealed-beam halogen headlamps also seen in that year's Pontiac Grand Prix GTP), tail lights, and front clip. Base models received a new rear bumper treatment. Instrument panel and gauge graphics were also slightly revised. The GSi version received a new spoiler and a larger DOHC engine which offered 10 extra hp.
• 1993: The wagonback was dropped, and the center console was fitted with a double-DIN radio. The hp rating of the base model dropped from 95 to 90 because of a camshaft redesign to allow more torque, creating a peppier engine.

Overall, there were six versions of the Storm; the GSi, station wagon and base models were all produced with both the original flip-up lights design and with the smoother look of the 1992 to 1993 model years.
