Here are some of the weirdest builds from SEMA 2021

Tipper trucks, or dumper trucks if you prefer and promise not to snigger at the name, are practical workhorses designed for doing a heavy-duty job. Until you slam them so hard down on the deck they need wheel-holes cutting into the load bay itself. Clever.

This appears to be an all-terrain buggy commissioned by a Greek god. One of the baddies. Hades of the underworld, probably. Given this contraption doesn’t appear to have a ladder attached we can only presume whoever drove this thing to SEMA is still inside, calling for help from the fire brigade.

The Porsche 914 is one of the more forgotten Porsche sports cars, forever in the shadow of the mighty 911. Course, if you festoon one with bullbars, a roof rack and enormous BF Goodrich tyres, someone with a vivid imagination can create the retro lovechild of a Cayman and a Cayenne you never knew you wanted. 

Some cars are a cross between two things, like a hatchback and a sports car, or a 4x4 and a convertible. Here we’ve got a classic, a tank, a steam locomotive and a snowplough all rolled into one. 

Next year BMW will finally give us what we’ve been waiting for: an M3 Touring. This E46 3 Series Touring was created by someone who couldn’t wait, and decided to upholster their wagon with a skate shoe box art and replace the engine with a nuclear power station.

We approve of the inclusion of a roll cage between the rear seats. Practical and safe.

One might argue an Audi Sport Quattro is already a work of surrealist art. But give one the explosion-in-a-paint-factory art car treatment and you have something worthy not just of SEMA, but the Louvre. 

Oh dear. Did we take a wrong turn and end up walking through a portal to the bad old days of the Geneva motor show? Whatever this Rolls-Royce Ghost did in a previous life to be subjected to this bodykit, those wheels and that coffee’n’cream with rose-gold colour scheme, we forgive it. 

Now this is an interesting build. It’s an energy-drink powered single-seater that claims to develop around 1,000bhp from its hybrid Honda V6 engine. Its makers claim it generates enough downforce to drive upside down and it’s so fast that piloting it for just one minute will make the occupant deliver forty per cent more angry radio messages.

Apparently it’s not road legal but there’s going to be a Netflix series dedicated to what they’re like to drive coming soon. 

There are many ways of being prepared for the zombie apocalypse. But both of these can’t be right. Wonder who has the louder horn?
