BMW M8 vs BMW 850I

What's the difference?

The right lane on Aussie freeways is occasionally referred to as the ‘fast lane’, which is laughable because the highest legal speed in the entire country is 130km/h (81mph). And that’s only on a few stretches in the Top End. Other than that, 110km/h (68mph) is all you’re getting.

Sure, a 'buck thirty' isn’t hanging around, but the subject of this review is a 460kW (625hp) four-door missile, capable of accelerating from 0-100 km/h in 3.2 seconds, and on to a maximum velocity somewhat in excess of our legal limit. 

Fact is, the BMW M8 Competition Gran Coupe is born and bred in Germany, where the autobahn’s left lane is serious territory, with open speed sections, and the car itself the only thing holding you back. In this case, to no less than 305km/h (190mph)!

Which begs the question, isn’t steering this machine onto an Aussie highway like cracking a walnut with a twin-turbo, V8-powered sledgehammer?

Well, yes, But by that logic a whole bunch of high-end, ultra high-performance cars would instantly become surplus to requirements here. Yet they continue to sell, in healthy numbers.  

So, there’s got to be more to it. Time to investigate.

Can a car company show off? It seems absurd; the kind of embarrassing, unedifying behaviour that only ego-driven, status-obsessed human beings engage in. And yet look at BMW’s new 8 Series, with its shinily silly cut-glass gear lever, its laser headlights, its outrageously powerful V8 engine and its bullfrog-but-beautiful stance - surely this is showing off on a corporate scale?

To be fair, when a car company makes a new range-topper - and BMW only applies the number 8 to its most special vehicles, think Z8 and i8 - it really is about making a kind of look-at-me statement. 

A car as obviously ostentatious as the M850i xDrive Coupe (and Convertible) has to appeal to buyers, even if it’s only a small and wealthy target market. And there is plenty that’s appealing about this old-fashioned yet modern-looking grand tourer, from the incredible way it accelerates to its luxuriant ride quality and decadent interior.

It would want to be impressive, of course, with a price tag of $272,900 (or $9000 more for the Convertible).

So, has the new 8 Series BMW got what it takes to separate the very rich from their hard-earned megabucks? We donned our shiniest shoes and went to the launch to find out.
