BMW 528i vs Mercedes-Benz C250

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?

If you’re picturing the premium mid-size segment in Australia, you’re almost certainly picturing Mercedes-Benz. Honestly, the premium carmaker has the kind of powerful and unquestioning stranglehold on the segment that would have despots and dictators turning green with envy.

The C-Class often outsells its nearest competitor by a factor of two to one. Even more impressive, that nearest competitor is another Mercedes, the CLA. Audi and BMW are left off in the middle distance, duking it out for third and fourth place.

So yes, the C-Class is a very important car for Mercedes. And this new one, updated for 2019, is even more so. It’s the first major update in the current car’s four-year lifespan, with a handful of exterior tweaks, some new key cabin technology and, most importantly, a new and clever engine option for its top-selling version.

So is that enough to keep the C-Class at the top of the mid-size pile?
