BMW 545i Sedan Review 2005

To me, it can be overly complex and distractive to the driver.

So I went for a long lesson; the one that BMW owners attend, with information about how the system works and what it can do and a hefty book as homework.

For an owner, or prospective owner, of a BMW fitted with iDrive, get prepared for some lessons because that's possibly the only way you'll get to appreciate how the system works and what it has to offer.

Not everyone may need the exhaustive list of iDrive options fitted to the BMW 5-series and 7-series, including systems such as audio, television, ventilation, navigation, communication and comfort.

By the same token, not everyone is taken by the styling of the 545i.

What everyone would appreciate is the car's ride quality and startling performance.

Though the sedan looks a bit bulky – it's a pinch heavier than a Falcon

the 4.4-litre V8 pumps out a hefty 245kW of power and a meaty 450Nm of torque at 3600rpm.

Matched to a six-speed auto box, with sequential change if you want it, the performance is outstanding.

The 545i also has superb handling, thanks to an active suspension system that works in concert with BMW's similarly active steering set-up.

Turn off the stability program and the big sedan lightens up beautifully, producing controllable oversteer with excellent steering feel.

Keep the stability program on and the big car holds a line through the corners with a near-flat stance. It is quite a remarkable and confidence-inspiring mount.

The big surprise through all this is how the passengers were virtually unaware of the car's speed and cornering prowess.

It remains quiet, unfussed and its performance potential is very understated.

Of course, the 545i has all the necessary trimmings.

Aside from a host of functions that can be tailored to the owner, the car sits on a long wheelbase for excellent rear head and leg room.

The seats are perforated leather, with optional cooling air fans in the front seats that dry your sweaty back while you make that business call on the hands-free phone.

The sound system is one of the best on the market, with a graphic equaliser that powers 10 speakers.

There's a sunroof; "comfort" seats with ventilation and electric lumbar, bolster and thigh adjustments, rain-sensitive wipers and 10 airbags.

The cabin design resembles the "edge" styling of the exterior, so it's restrained only by the dark colours chosen by the interior decorator.

It's a great car, but don't think all the goodies it offers comes at an affordable price. At $150,000-plus, it's the perfect express for the executive in a hurry.
