the sad truth Chevy still builds and sells V8-powered rear-wheel-drive sedans. Just not in the United States. What you're about to read will not make you happy. In fact, it may make you sick. Don't say we didn't warn you. Okay, here it is. Chevrolet builds and sells V8-powered, 300-plus-horsepower, rear-wheel-drive sedans in the Middle East. It also sells what is essentially a V8-powered, rear-wheel-drive El Camino in Australia. That's right, Saudi Arabians and Australians are able to enjoy such machinery, while Americans are stuck driving V6-powered, front-wheel-drive pedestrian sedans. What gives? Your guess is as good as ours. At a recent GM Powertrain event at Irwindale Speedway in Irwindale, Calif., we were able to drive two of these overseas-marketed vehicles, the Middle East market Chevrolet Caprice LTZ sold in the Middle East, and the Holden Ute marketed in Australia. (The Chevrolet Lumina, which is also sold in the Middle East, was not sampled.) Both vehicles managed big smoky burnouts and quarter-mile runs of little more than 15 seconds. We were so impressed we asked GM's public relations staff for information about these cars, but they didn't have much to offer. The best they could do was give us a GM Middle East Web site address, www.gmme.com. There we learned more, but not as much as we would have liked. And when it came to the Ute, GM Communications offered up nothing. But here's what we know.
