2022 BMW M4 Summary

Few cars carry the burden of expectation more than the BMW M3 – and, by association – the two-door versions latterly rebadged M4. Porsche 911 definitely. Mazda MX-5 probably. Ford Mustang maybe. Icons all.

Since the arrival of the left-hand-drive-only – thus it never officially came to Australia – E30 3 Series two-door original in 1986, it’s become the benchmark for which all others follow, and regular finalist in any given ‘greatest sports car of all time' listings.

Except… it hasn’t always turned out that way.

After the visceral E30 M3, it’s been a rollercoaster ride of disappointment and elation: by 1992’s patchy E36 arch enemies Audi and Mercedes-Benz were chiming in, only to be swept aside by the exquisite E46 M3 from 2000. But then its 2007 E90 and 2014 F80 successors both missed their marks for reasons we’ll go into later, leaving us with 2021’s G82/3 generation.

Does the latest two-door M-car return to form? We take a look at the M4 convertible, which simultaneously rediscovers the fabric roof and adopts all-wheel drive (AWD) for the first time.

Glorified blow dryer or glorious mind blower? Let’s see.

2021 BMW M8 Summary

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.
