The car world’s worst April Fools

April 1: the day the world's car manufacturers take a break from, y'know, manufacturing cars, and turn their attentions instead to amateur comedy.

And from BMW mouthguards to colour-changing Skodas, 2015 saw a bumper crop of exclamation-mark-laden, acronym-ridden punmanship from around the globe.

For those of you of a masochistic stream, we've rounded up the very worst of the car world's April Fools ‘pranks' into one side-splitting gallery.

Click through for 2015's biggest offenders (and, we suspect, a bunch of comments along the lines of: "Know who the real April Fools are? YOU GUYS! UNSUBSCRIBE!").

Oh, and a completely plausible V8-powered AMG Sprinter van, which we assume will reach roads very soon.

The gag: A BMW-designed rugby mouthguard that 'uses tyre tread technology for extra grip as well as BMW's signature "kidney grille" between the front incisors acting as an elegant respiration vent'.

The clanging pun: Dr Uwe Gotobekidin, Head of Product Fabrication, said: "We've loved getting our teeth into this unique opportunity to collaborate with the sport!"

Hilarity rating: Multiple molar extraction

The gag: A ‘colour-change system that allows motorists to alter the hue of individual panels via a new menu on the touchscreen infotainment system.'

The clanging quote: "When drivers are feeling in a jolly, spring-like mood, they can switch the whole car to a bright yellow. On the other hand, if they are feeling sad because their cat is unwell, they can switch it to black."

Hilarity rating: Feeling a bit green

The gag: a button that turns off all driver assistance systems and increases steering and pedal resistance ‘allowing commuters to get their very own workout at the wheel.'

The clanging anagram: Personal trainer Raol Pofil, who runs Le Mensonge Fitness Centre in Paris, said, "Nissan asked me to develop a programme that would help drivers burn more calories and develop leaner bodies without leaving the comfort of their cars."

Hilarity rating: Our flabby sides are splitting

The gag: A miniature version of VW's Caddy van that ‘can be parked at right angles to the kerb and has a turning circle of just four metres - a figure many bicycles struggle to match.'

The clanging strapline: It's not about the size. It's about what you do with it.

Hilarity rating: Very Mini

The gag: A slightly chubby Daniel Craig lookalike pretends to take delivery of his new Lotus Evora 400.

The clanging giveaway: His waistband

Hilarity rating: Can't-afford-an-actual-celebritastic!

The gag: A Vauxhall Vivaro taxicab that ‘features two gas-fired spit rotisserie grills, salad bowls integrated into the arm rests, chilli dispensers and of course a tasty selection of sauces.'

The clanging pun: "We really believe we've given our customers something to sink their teeth into."

Hilarity rating: Skewered

The gag: a Mercedes Sprinter van that's ‘powered by a 503bhp handcrafted 4.0-litre biturbo V8 which means it's also ready to haul a lot more than just cargo.'

The clanging pun: There isn't one. They're German.

Hilarity rating: Not funny, but an eminently sensible idea and one we expect to reach production very soon. Trust the Germans to do April 1 properly.
