No motor show is complete without a ridiculously fast, completely unaffordable hypercar. The Frankfurt Motor Show had the Mercedes-Benz-AMG Project ONE, a two-seat hybrid with over 1,000 horsepower and a top speed of 350kph (217mph).

Described as "a Formula One car for public roads", it was unveiled by three-times Formula One world champion Lewis Hamilton. It has a turbocharged 1.6-litre V6 engine that can rev up to 11,000 rpm – a few thousand short of an F1 car – and four electric motors.

And then there's the Bugatti Chiron, which has just set a ridiculously fast world record, travelling from zero to 400 kilometres an hour (249mph) and back to a standstill in just 42 seconds.

Half as fast as the Bugatti but far more affordable and far more stylish is Ferrari's new Portofino. At €196,000 (£176,658) it is is 3% more expensive than Ferraris's current "entry-level" supercar – the California T – and 3mph faster.

But Frankfurt is not just for petrolheads. Many carmakers unveiled the low-emissions vehicles and technology strategies they hope will let them profit from the sweeping changes due to hit the industry in the next few years. Volkswagen announced a long-term electrification campaign, saying its brands would introduce 80 new electric vehicles by 2025. It said VW will offer a fully or partially electric version of every car in all of its brands by 2030.

Small SUVs are a popular theme at the show as manufacturers crowd into a segment that has proven a winner with consumers.
