g and a lane change, and can be turned off if desired. The price rises only $100 over 2005.

The Q45 is available in a single trim line, called the Premium; it uses a 4.5-litre V8 also used in the M45 and FX45.

The Q45 comes with a 4.5-litre V8 and five-speed automatic transmission. Standard features include 18-inch chrome-finish alloy wheels; heated outside mirrors with memory, selectable left/right auto reverse tilt-down, puddle lights and driver’s side auto-dimming; seven-lens Xenon headlights; DVD-based navigation system; fully automatic trunk open and close function; performance-tuned active dampening suspension; tire pressure monitoring system; dual-zone climate control; navigation system with seven-inch LCD screen and rearview monitor; heated and cooled front seats with ten-way driver and eight-way passenger adjust; heated rear seats; six-CD/cassette Bose system with eight speakers; voice recognition system; power rear and manual rear door window sunshades; and laser-based intelligent cruise control with preview braking feature.

Although it’s getting a little long in the tooth, the Q45 is still a superb sedan. With the new M45 handling the sports sedan side of the market, the Q45 is well-placed as a luxury model – it dropped its Sport model in 2005 – but it nevertheless offers excellent driving dynamics and fine handling, with good acceleration and a well-mated transmission. It’s a great car to drive, but there’s no shame in being relegated to the back seat, where creature comforts make long drives welcome. It’s a lot of money, but it’s also a lot of car.
