This was a fastback version of the Civic which still managed to weigh in at less than 2,000lbs, early models weighed as little as 1,700lbs. A wheezy 58-horsepower engine served in the base model, but in 1988, the CR-X Si became available in the US, complete with a 105 horsepower engine. Although the
Volkswagen GTI had already emphasized the importance of power-to-weight ratios several years earlier, the CR-X Si showed that offering the same power and weight but for a lower price was even more important. Economics played an important role in the popularity of the Civic as a tuner car, probably more so than any other car at the time.
