This small sedan has responsive handling and a steady, compliant ride. Road noise is pronounced. The 1.8-liter, four-cylinder engine is refined, works well with the smooth five-speed automatic, and returned 28 mpg with the automatic and 31 mpg with the manual. Instruments are arranged in two tiers, with a high-mounted digital speedometer. Standard safety equipment includes ABS and curtain air bags. Crash-test results are impressive. The Hybrid got 37 mpg overall. The Si is a very quick, sporty, hi-revving model that is fun to drive. A natural-gas powered model called the GX is also available, but it has a short cruising range and a tiny trunk because of the tank holding the compressed gas.
