Stricter WLTP emissions testing spells early end for the current M3

BMW will end production of the F80-generation M3 in August because the car won’t conform to Europe’s more stringent emissions limits.

A brand spokesman told Autocar that the super-saloon model, which produces 425bhp from its turbocharged straight-six, would need a new particulate filter in order to meet the requirements of the new Worldwide Harmonised Light Vehicle Test Procedure (WLTP).

The rehomologation process that follows such a change would prevent the updated M3 from making it to market before the next-generation 3 Series is revealed in October. As such, BMW has chosen to pull the car early and end its production alongside the rest of the 3 Series range, rather than keep it in production for longer the way it has with its forebears.

New WLTP and RDE tests explained

No such scenario will be applicable for the M3’s two-door equivalent, the M4, because that car and its 4 Series siblings will remain on sale into the following year. The spokesman said that the M4 would go off sale “for a couple of months” while it is rehomologated, but that it would return to showrooms with its WLTP-certified filter.

Opinion: the price we'll pacy for WLTP testing

The filter will reduce the car’s output of emissions to bring them below the maximum level required by the WLTP, but the spokesman said that performance would be unaffected. No other changes will be made to the tweaked M4, so it'll still be good for a claimed 4.3sec dash from zero to 62mph.

The decision to retain the M4 will also have been driven by its popularity. In Britain, close to 2400 M4s were sold in 2017, 700 of which were convertibles. Just 1100 M3s were sold in the UK last year.

The next M3 is due to be launched in 2020. It’s expected to use a reworked version of the current car’s engine that produces 456bhp - 21bhp more than today's M3 Competition Pack.

Our Verdict

BMW M3

You’d imagine that a higher roofline and four doors would hinder the BMW M3 saloon’s capabilities compared to the M4, but you'd be wrong

The sooner BMW gives the chop to that S55 motor the better. Has BMW ever served up so much horsepower with such disproportionate lack of 'soul' and 'essence of Munich' ? Not in my living memory.  The N55 has more BMW-ness than the S55 could dream of. Undoubtedly the worst M-Power unit......ever.

Bimmerboost also describe that engine as the worst ever too.  Search for them and the crank hub spinning problem.

 

It's funny how BMW are certifying the engine in one car but not the other.   Surely that's just a paper exercise without much formality involved?

Yeah made laugh...
Seriously though, costs. Low numbers and parent model at the end of its cycle.

But underneath they're essentially the same.   They both share the same platform, same running gear, same engine.   I just don't find anything plausible in their reasoning.

Do some research into it.

How the hell does 'Worldwide Harmonised Light Vehicle Test Procedure' get officially abbreviated to WLTP...?

A sorry combination VAG lies and BMW not really giving a monkeys about the petrol engine in the first place being as the "master plan" was to turn Europe into "diesel city"...and they would have gotten away with it if it wern't for those pesky yanks

Sam Sheehan, youre writing complete nonsense - a particulate filter does not "reduce levels of nitrogen oxide" a NOx trap or AdBlue/Urea does that, a particulate filer reduces particulates. The clue is in the name. Really, how can people take you seriously when you get basic things like this wrong ?

XXXX just went POP.
