A Toyota Prius Plug-in has returned a 698mpg fuel consumption figure on an economy run around the 12.8-mile Nürburgring Nordschleife.

The Toyota Prius Plug-in's claimed combined cycle fuel economy figure is 134mpg, but the petrol-electric hybrid almost completed the whole lap on EV power alone, with the 1.8-litre petrol engine only engaging during on a long uphill climb.

New York motorshow update: The covers are finally pulled off the second generation Toyota Prius Plug-in Hybrid

The car used for the economy run was upgraded to TRD (Toyota Racing Developments) specification. This includes lightweight 18in alloy wheels and low rolling resistance tyres, uprated suspension, aero-enhancing front and rear bumpers and a rear spoiler.

The run took place during a Nürburgring public track session, meaning the car had to comply with all the circuit rules, including the minimum average speed of 37.2mph (60kph).

The lap took 20 minutes and 59 seconds – more than three times longer than the production car lap record of 6 minutes 57 seconds set by Marc Lieb in a Porsche 918 Spyder hybrid last September. 

Toyota has previously broken the Nürburgring's lap record for electric vehicles with its EV P001 and P002 racers. The battery cells from the EV P002 were used to fully charge the Prius Plug-in via a charging truck prior to the economy run.

Toyota Prius

The Toyota Prius is an easy and very visible route to greenness, even if its reputation as the minicab of choice for UK drivers is now impossible to shake off

Just shows how good the plug-in is getting. That works out to less than a penny a mile. They should now be working on the electric only range to get around 50'ish miles which is most people's daily needs most of the time

This does show how good plug in hybrids are getting it just goes to show how stupidly inaccurate mpg figures are over a short distance. Even at the 134 mpg figure i bet if you dropped the boss of toyota in the middle of nowhere with one of these and a gallon of fuel and said the petrol stations 100 miles that way he wouldnt try it.

Suddenly it makes that £100k that VW want for its XL1 monstrosity seem a bit silly.

Toyota - albeit the father of the hybrid car - must be feeling the heat following the awesome new hybrid arrivals from Europe.
I do hope sincerely that the new Prius will reflect Toyota's competitive streak if it wants to stay at the lead of the green car.

I'm a big fan of EV technology, but these marketing tricks only serve the purpose of flat-earthers climate-change denying morons... Of course a slowly driven EV will get massive mpg on a 14 mile track, but that doesn't mean anything.
The 918 record is infinetly more significant. If they want to show how good electric technology is, they could show how a plug-in car could get incredible mileage on a normal, real (non EU) daily basis, which it could. Or how they can get mind bending performance, which they did (P1, LaFerrari, 918).
Not this, please. EV buyers tend to be (a little) less moronic than sporty SUV buyers, so don't treat them as such!

Meaningless figures, pointless publicity. I managed to get 1000mpg out of my X5M when I pushed it down my drive last week. But then I am a moron.

It would be more interesting to learn how much fuel the car used on its second lap when the battery charge was depleted. Arguably with a range of 12.5 miles at speeds of up to 62 mph, it should not have used any fuel at all on the first lap. Don't forget, we're not talking about a standard Prius here, but one modified with special wheels and tyres and aerodynamic aids.

Or to play Toyota at their own game...

Why not quote the mpg figure for that uphill climb whilst the engine was engaged? I'll tell you why, because a bog standard 1.6tdi VW Golf would make the consumption of the Prius look positively thirsty.

So this car used very few fuel over a dozen of miles. And drained it's rechargeable batteries while doing so. 2 obvious comments:
- once the batteries are empty, fuel consumption will obvious increase, so it only works for short journeys (if you only do short trips, though, all good for you!)
- electricity on a RECHARGEABLE hybrid is not self produced. You have to plug the car to leave with full battery. But Toyota "forgot" to mention the electricity consumption during this exploit. If you do so, then a Leaf or a Zoe would get an infinite mpg!
