A test Q45 accelerated to 60 mph in a brisk 7.2 seconds. Midrange power is similarly ample, aided by a velvety-smooth, responsive and refined automatic transmission. Fuel economy is less inspiring. We averaged only 15.4 mpg in a driving mix that included a lot of rush-hour commuting, and 17.6 mpg in a session that covered more highway miles. Compared to the prior Q45, the new standard model is less agile. Road manners are competent enough, but hardly sporty. This version also feels more roly-poly on tight, twisty roads--closer to the Lexus LS than to BMW's 5-Series, for instance. Slightly numb on-center steering feel doesn't help on this score, either. Suspension damping is soft enough to allow a fair amount of nosedive during hard braking. Otherwise, the brakes perform admirably. At the same time, you can expect something close to a "magic carpet" ride, with outstanding impact absorption. Body control is better in the Touring edition, however. This "Q" is quiet, without question. Cruising is hushed, with little noise intruding from the road, wind, or engine. Passing over railroad tracks and other hazards generally produces a feeling of solidity. Though smaller outside than the prior "Q," this one is a little roomier inside. Despite the dimensions, though, lanky back-seat occupants must ride with knees-up if a tall passenger happens to occupy the front seat. Head room in back is only adequate, too. Front seats are roomy and comfortable, with enough adjustments to accommodate occupants of nearly any stature. Visibility is good except over-the-shoulder, where wide rear roof pillars serve as obstacles. Although the dashboard looks somewhat uninspired, it's orderly and convenient, though a few controls are cryptic or hidden. The sedan's trunk is wide but not very long, offering space for about four medium suitcases plus a few odds and ends.

Value for the Money
Though impressive overall and appealing in a number of ways, bland styling and inadequate cargo room help make the latest Q45 a less-than-scintillating competitor.
