It’s a rare thing to be able to put your foot down in the BMW 545i. You need plenty of space, a low gear so you’re not advancing at absurd speed when you hear the V8 issue its distant, creamy, hammering wail, and preferably no witnesses, either human or electronic. This car is not supercar-fast, but it’s more than quick enough for today’s conditions, in the UK at least.
The 4.4-litre variable-valve-timed V8 yields 333bhp – 47bhp more than the outgoing model – and 332lbs ft or torque at 3700rpm, which is sufficient to thrust the manual 545i to 60mph in 5.8sec and on to a governed 155mph.
Equally heart warming is the fuel consumption, which on one 320-mile motorway run exceeded 28mpg. And this was in the six-speed automatic version. Admittedly there were no full-throttle moments, but it demonstrates what’s possible if you can resist.
Such efficiency is not just down to the engine and transmission, but to the Five’s relatively light weight. Its styling has proved so distracting that the efforts of BMW engineering department, which has managed to build a car that actually weighs less than its predecessor – a real rarity these days – have gone ignored. Building the nose structure from aluminium is one reason, and most of the running gear from the same material another, but much of the reduction stems from obsessive cheese-paring.
