2010 Lexus LS: Road Test

ACCELERATION

Smooth and ample power at any speed. In Consumer Guide testing, an LS 460 did 0-60 mph in 5.6 seconds. The silky automatic transmission is generally responsive, but a deep stab of the throttle is required to coax a downshift for maximum acceleration. The 460 Sport Package's paddle shifters enable on-demand gear shifts for better responsiveness in spirited driving. Hybrid 600h models are heavier than conventional LS models, so they are only slightly quicker 0-60 mph. The gas/electric drivetrain calls little attention to itself. No opportunity yet to test an AWD LS 460.

RIDE QUALITY

The base suspension is pillowy on most surfaces with noticeable highway float. The available air suspension's Sport setting induces some body jiggle. The Sport Package's 19-inch wheels and sport-tuned suspension bring a bit more composure with little detriment to ride quality.

QUIETNESS

One of the quietest cars on the market. The engine is nearly silent at idle and emits a subdued growl under aggressive acceleration. There is virtually no tire, road, or wind noise.

DETAILS

Top-quality materials with numerous soft-touch surfaces highlight the understated design. Numerous options and option packages allow a degree of personalization and deliver some extra-opulent features.

ROOM/COMFORT (REAR)

Adult-roomy here, too, though foot space is tight with the front seats fully back in the standard-wheelbase model. The long-wheelbase model adds its length in rear legroom. The seat blends fine support and soft padding in the outboard positions. A middle rider will fit, but the contour of the cushion means passengers will be cramped for headroom; they also have to straddle a bulky drive-line hump. The available Executive Seating Package combines upgraded leather with indulgent amenities such as a massaging right-side seat and body-temperature sensors linked to the climate control. For some passengers, the Executive Seating Package's leg rest can lift the occupant's feet into the seat ahead. Also note that with the leg rest extended, the front-passenger seat cannot be occupied.

VALUE WITHIN CLASS

LS base prices start below those of the Mercedes-Benz S-Class and Audi A8. It is less sporty and more comfort-oriented than those German rivals, but Lexus' flagship is a Best Buy choice for its power, refinement, standard features, and optional gadgets. The new-for-2010 Sport Package delivers a more-engaging driving experience for rear-drive 460 models, and the hybrid 600h remains an extremely pricey technological tour-de-force.
