If this year's CES in Las Vegas was a platform for automotive manufacturers to show off their wildest science-fiction creations, Detroit was the analogue antidote - a feast of high-performance metal, much of it powered by old-fashioned fuels and noisy engines.
But nestled in amongst the V6 and V8-powered monsters were a number of innovative concepts, hybrid performance machines and futuristic fuel-cell vehicles.
Here's our pick of the most interesting.
Say hello to the ultimate performance Ford: the all-new GT. Take one extremely lightweight carbon-fibre and aluminium shell, slap a brand new 3.5-litre EcoBoost engine under the rear window and marvel at a 600bhp machine that will scare the pants off Lamborghini and Ferrari owners.
Expect a price tag in excess of £150,000-£200,00 when it hits roads in 2016. Can't wait or afford to get behind the wheel? Fear not, as the Ford GT will star in the upcoming Forza Motorsport 6 XBox One game, so at least you can indulge your GT fantasies, even if it is only virtually.
Modern motorists are a fussy bunch; they want performance and thrills without the earth-battering emissions. Honda thinks it has cracked it with the upcoming NSX supercar; a re-imagining of the 1990s original that is powered by a potent V6 petrol engine and two electric motors.
The result is a staggering 550bhp and cutting-edge handling thanks to the brilliantly named Super-Handling All-Wheel-Drive system. Order books for the £100,000 stunner open this summer, so have those credit cards at the ready.
Volkswagen Cross Coupe GTE
Do you fancy adding a bit of hybrid spice to the school run? Why not cross fingers and toes and hope that Volkswagen brings this petrol/electric behemoth to the UK. It's pegged for US-only release at the moment and will feature a stonking 355bhp V6 hybrid petrol engine when it goes on sale. There's also a new infotainment system inside, which is controlled via a 10.1-inch touchscreen, plus a 12.3-inch Active Info Display – similar to that recently previewed on the new Passat – that produces high-quality interactive graphics instead of bog-standard gauges. Neat.
Honda is going full steam ahead with hydrogen fuel-cell technology as this latest futuristic concept proves. The FCV builds on the groundwork already laid by the current FCX Clarity model, which is no longer available to lease by US and Japanese customers, and 2013's FCEV concept.
The abbreviations get confusing but the latest FCV has basically taken old fuel-cell technology, shrunk it and tweaked it so power output is up 60% over the current FCX Clarity model. Are you still with us? Well, Honda engineers claim the FCV can be topped up from a 10,000-psi hydrogen nozzle in just three minutes, while offering a 300-mile range.
Let's hope Toyota's recent act of patent altruism improves the hydrogen-fuelling network, otherwise the FCV could just be another flash-in-the-pan alternative fuel vehicle.
