BMW M4 CSL rendered

Another week, another head swivelling rendering that's caused us to down tools and fawn helplessly at our laptop screens. After last week's Mercedes AMG GT Black Series mockup, internet doodler and motoring mischief maker rc82 workchop has used his electronic crayons to draw up a BMW M4 CSL.

Like the AMG GT Black, it's not real. But this is even less real, figuratively speaking - while a hardcore, bewinged Merc is no doubt in the product plan, BMW has ruled out the return of the CSL badge on the M3 or new M4.

Here's what Matt Collins, product manager for BMW's small to medium cars, told us back in January: "Rather than doing a halfway house to begin with, and then rolling out a CSL, we thought we'd make the ‘real' car as light as we possibly could. So we've no plans whatsoever to make a lighter, harder version just yet."

We're rather hoping he sees this and campaigns for a change of heart. Perhaps influenced by BMW's reticence, rc82 really hasn't held back on this one - note the huge intakes behind the doors, the heavily sculptured bonnet and the influence of the BMW i8's fantastically wild aero on the rear flanks. The front splitter would no doubt happily and expensively remove itself at the first sniff of a speed bump, too.

And rc82 - creator of the nuts Bugatti-Beetle - reckons he'd like to have spent more time on this particular illustration. What extra adornments would that have led to? The mind boggles.

We're becoming quite a fan of rc82's work. Quite how keen BMW and Merc's product planners and marketing people are to see it is another matter entirely...
