BMW 540i vs BMW M140I

What's the difference?

Eco-friendly vehicles are the leather pants of the new-car world; it takes a lot of money to make them look good (but people who own them think they look fantastic regardless). If you don't have a gazillion dollars to drop on a Tesla,  then it's a one-way ticket to Prius town. And really, who wants that? 

But what if it didn't have to be that way? Behold the BMW 530e iPerformance.

Seemingly tired of waiting for the Australian Government to introduce any sort of meaningful subsidy for green cars, BMW has made the choice simple: you can have a petrol-powered 530i for $108,900, or opt for the plug-in hybrid 530e for... $108,900. This is truly revelatory thinking.

There's no specification penalty, either, and the hybrid will power to 100km/h in an identical 6.2 seconds, so you're not even any slower. But you are sipping less fuel, emitting less C02 and basking in the general smugness, and sweet silence, that comes with feeling like you're saving the world.

So what's the catch?

If you think it’s a Mercedes-Benz A-Class you want or maybe an Audi A3 Sportback or even a Volkswagen Golf, then stop and read this first before making a purchase.

The BMW 1 Series alternative isn’t just another prestige little car, because there are some fundamental differences between this 1 and those others, and they could cause you to totally rethink your decision.

If you’re already keen on getting a 1 Series then you need to read this, too, not only to help you find the right one, but also to alert you to what might be a couple of uncomfortable truths.
