The group is headlined by the 'Ultimate Super (...Special Extreme Terrific Fantastic? - Ed) Beetle' concept, tuned together with APR Performance and the VWVortex collective.
Overhauling the new bug's 2.0 litre TFSI petrol engine, APR boosted output from 150 to a whopping 372kW, achieved through the addition of a new turbocharger and intercooler setup, a high-flow cylinder head and intake manifold, an ECU tune, and stronger pistons.
The Ultimate Super Beetle also picks up Volkswagen's 4Motion all-wheel-drive, taken from the Golf R.
There's also a new clutch, new suspension, six-piston brakes, 19-inch wheels and a sports body kit.
The other Beetle concepts on show at SEMA include the 300kW 'Beach Battle Cruiser', a dumped Rotiform-prepared Beetle and a 'chop top' bug developed by Galpin Auto Sports.
Lastly, FMS Automotive put together a special restoration for the 1956 Beetle, and H&R gave the Golf R a going-over.
Set to go on sale in February next year, the new model will replace the previous ‘New Beetle’, which disappeared from local sales charts in 2011.
Local models will employ the 1.4 litre twincharger 118TSI four cylinder engine found elsewhere in Volkswagen’s line-up.
Transmission choices will be either six-speed manual or seven-speed DSG automatic, while fuel consumption for the six-speed manual version on display is listed at 6.8l/100km.
