What's the difference?
Andrew Chesterton road tests and reviews the new BMW 5 Series 520d, 530i, 530d and 540i sedans with specs, fuel consumption and verdict at its Australian launch in Victoria.
When we're all living under the cruel rule of our robot overlords, the few remaining human historians will track the genesis of our downfall to the technology explosion that occurred in 2017's new-car market.
Never before have car companies focused so hard on producing cars that can't just be driven, but that can drive themselves, negotiating corners, unexpected obstacles and changing traffic conditions without ever needing to consult the human actually sitting behind the steering wheel.
And BMW's all-new 5 Series sedan takes yet another a step forward, eliminating the need for said human to even be sitting in the car. Owners can instead move their 5 Series in and out of tight parking spaces simply by pressing a button on their key.
The Active Key function is admittedly a $1,600 cost option, but it proves the techno-focus applied to the seventh-generation of BMW's executive express, which will land in Australian dealerships this month. Every car is also fitted with what the German brand calls its personal co-pilot; a series of nifty cameras and radars that allow the car to be driven completely autonomously for spells of 30 seconds.
But the question is, has all this new technology come at the cost of regular, old-school driver enjoyment?
Over 44 years BMW has produced more than 15 million examples of the 3 Series. That's roughly one every minute and a half... for over four decades.
And the latest, seventh-generation version of what the famous German maker defines as the "heart and soul" of its brand has landed in Australia.
The new '3' is longer and wider. It's also claimed to be slicker aerodynamically, up to 55 kilos lighter, more fuel efficient, and faster.
And it'll need every advantage it can muster to take a chunk out of its arch rival, the all-conquering Mercedes-Benz C-Class.
Sleek and attractive in the city, engaging on a country back road and with plenty of clever technology, the 5 Series sedan ticks all the right boxes as an executive express. If you can stomach the price hike, the six-cylinder 540i is our pick of the bunch.
Despite BMW's wholehearted embrace of the SUV its 3 Series is still a critically important model for the brand in Australia. And this new version certainly has the spec and tech to take the fight up to Merc's C-Class. And if you're in the happy position of making that choice, it's now a whole lot harder. For our money the 330i marks the sweet spot with extra performance, safety tech and standard features for only a fraction more than $3k over the 320d entry-point.
