Prius on the motorway

obi604

My questions relates to a 2010 Prius.

I know they are good around town and in start stop type traffic.

But on a motorway with cruise on at 120 k an hour - from an Mpg point of view, would they just be the same as any other 1.8 litre petrol car?

i.e. no real advantage to a Prius at motorway speeds?

I think on aerodynamics and the fact that it will charge the battery for later use as you drive that there's not a single 1.8 that would be better than it. A diesel 1.8 would be another story.

They primarily setup for urban style driving so they are not going to be at their most efficient doing motorway driving so I'd expect them to be no better than a regular petrol car with a similar sized engine. Given you will probably pay a premium for a Prius I'd don't see the point of buying one over a regular 1.8 petrol car if your using it for some motorway driving.

With cruise at real120kmh (indicated will be a bit more), the MK3 will take 5.5-6.0 l/100km

Sure that’s fairly decent isn’t it ?

It is good enough for me....

Drop to 100 on the motorway and it would probably do much better than 5.5l/100km

Not sure on a 2010 model but the 2016 model I had would run on battery alone up to 105km/h so could pulse and glide across the M50.

I used have a 2010 insight, basically same MPG, they're fine on the motorway ,keep it reasonable,90/100 km per hour to achieve decent MPG, regularly hot 60 plus

That’s very good. I doubt an ICE car with a 1.8 litre engine and automatic transmission would get near this.

Edit: I mean a 1.8 litre PETROL engine here.

I got 50mpg from a hybrid CHR and a 1.6 diesel Octavia returned 55mpg in the same trips. Maybe 70% motorway.

True, insights also auto but hybrid

Almost any modern beemer or VW diesel auto will

Until they die out of oil starvation or timing chain failure

1.8 or similarly taxed petrol won't

Nope but theyll accelerate in less than 2 days.
A 1.8 or 2.0 modern petrol beemer or VW prob accurate to 100 in 7 or 8 seconds

Its horses for courses.

No point grabbing the cars you want to compare to.


Want an economical ICE Toyota. Buy a 1.4 diesel auris. 4.5 l per 100 and substantially cheaper than Prius.

Who on earth wants to sit on a motorway at 100kph? I get 8.8l/100k with aircon and cruise on and am delighted. 18-20l/100km in town

As a prius owner I would suggest a diesel for purely motorway driving especially if you have even the slightest heavy foot. but if you have a good mix of driving and are willing to learn to drive the prius you will be better off in the long run with the prius, and you don't need to drive under the speed limit. I do about 20-25% town driving and the rest motorway, I get approx 51 to 53 mpg on a 2009 prius, I drive at the speed limit but am cautious enough in my driving style.

One thing to also factor in is that there will be very little issues with them. They really are a super car

I've gotten 4.7-4.8L going to the airport in my Golf. Usually get around 5-5.3 on a motorway journey and 5.5L on my work commute, closer to 5.3L if I baby it. I can manage 5.3-5.5L on a return trip from Lucan to the city center too. Some days it's closer to 6L with traffic.

It's not as good as I was hoping but I can't argue with that for a 1 litre petrol.

I live and work in Dublin so any chance I get to do 120kph I take it. I know fuel economy tends to drop off past 100kph but I'll still get decent economy as I'm not stuck in the suburbs going through roundabouts every 5 minutes.

I suppose if you're doing lots of motorway driving it might be worth the savings but it's not a huge deal to me. I tend to take it easy when driving so my overall habits help with fuel consumption so I don't worry too much about doing anything over 100.

I have a drive to Galway in April for a wedding and I'm curious to see what kind of fuel economy I'll get for that.

Na 'twas some other bloke. Never stopped going on about the savings he was making!

TSI, can't afford a TFSI/Audi

At 110hp it's not a fast car by any means but it's nifty enough for an econobox, it's surprising at how quick it can move at lower speeds especially with the DSG gearbox. It does run out of steam around 100kph though. You'll easily get to 120 (and beyond) but acceleration does seem to taper off at 100.

It's not as whiney as people make it out to be either considering it's a 3 cylinder. I know a lot of people wouldn't touch a 1 litre in a Golf or a 3 cylinder but it's definitely worth a test drive for anyone considering. I would have liked the 150hp though just for a little more poke but as a daily driver I love it. Went for a 2 hour drive in the mountains just a few days ago

Motorway use up to 130 kph sees 5.9l/100km.

Probably half the price of a Prius. .... ...

5.9 isn't a big deal. I have averaged 5.4 in a 520d over 83200kms since I changed from an 06 Prius. The Prius averaged 5.2 over 86000kms.

I would have expected better from the Megane.

Driving style makes a huge difference.
