Along with the previously mentioned redesign the big news for 2003 is a 100 cc larger displacement 4-cylinder engine. Now at 1.6-L, the Rio produces a much healthier 105-hp, 9-hp more than last year's 96-hp. Torque is up as well, from 98 lb-ft to 104. While noticeably improved under full acceleration the pace is hardly blistering, especially when the engine is joined with the optional ($1,000) 4-speed automatic transmission - a 5-speed manual is standard. One thing that did impress me, however, is the automatic transmission's smooth shifts and well-matched intervals. In the previous Rio I tested, a 2001 model, I experienced a discomforting clunk from Park to Drive and Drive to Reverse. The 2003 car is refined in comparison.
The Rio RX-V handles pretty well too. Of course, its skinny P175/65R14 all-season tires on alloy wheels hardly optimize its independent front and semi-independent rear suspension setup, but their low rolling resistance helps to increase fuel economy. Front and rear anti-roll bars improve lateral stability, enough so that during fast sweeping corners it remains fairly flat and reasonably composed. Its standard power steering helps keep the Rio tracking well at high speeds too, while decreasing effort during parking. All in all it's not necessarily a rewarding performer, but can hold its own if you're in a rush.
