To check out the Envoy XUV's willingness to tow, we hitched up a Ski Nautique on a single-axle trailer. The test vehicle had the standard 4.2-liter DOHC in-line-6 engine-a 5.3-liter V-8 is available for an extra $1,500. The standard engine is a serious overachiever and pumps out an enthusiastic 275 hp, but lock the tach needle at the high end of its scale to enjoy reasonable performance. Without the 4,120-pound load, reaching 60 mph took 9.9 seconds; with the boat and trailer, we measured 17.6 seconds. The engine doesn't hesitate to answer a kick of the throttle, but another gear would be appreciated-the automatic transmission has only four forward speeds. Passing performance is enough to keep you apace of traffic.
