BMW M135i vs BMW M140I

What's the difference?

When the iPhone first appeared just over a decade ago, I can remember thinking a phone without buttons would be a giant pain in the neck. Until I used one, and now the idea of a keypad phone sounds akin to starting a car with a crank handle.

The new 1 Series is likely to offer most buyers a similar revelation, with its move from the BMW-traditional rear-drive layout to more conventional front and all-wheel drive. That is assuming you gave a damn in the first place, as I suspect it’s only hardcore BMW traditionalists that care about a rear-drive premium hatchback in 2020.

And that’s not who is buying the 1 Series, with the Bavarian brand’s cheapest model intended to appeal to younger buyers who are more likely to care about connectivity, practicality and personalisation options than the excitement of losing grip from the rear. It certainly hasn’t stopped plenty of people from buying 1 Series-rivalling A-Class and A3s from Mercedes-Benz and Audi over the years.

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.
