BMW 520d vs Cadillac Optiq

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?

The lonely Cadillac Lyriq finally has some company, with the iconic US brand tripling its range down under with the launch of the much bigger Vistiq (which we've already tested) and this entry-level Optiq, which Cadillac describes as the gateway to its electric family.

It's a medium all-electric SUV with plenty of equipment and – depending on whether you see it as an established premium player or another newcomer brand – pretty sharp pricing.

Cadillac says it has the German big three in its sights with the Optiq, so how does it stack up?
