The most economical new cars on sale based on low emissions and best fuel economy


The most economical cars you can buy (© Smart)

Fuel economy is a hot topic and car firms are responding by making their cars ever-more efficient. It is now common to see new cars returning more than 80mpg: even mainstream family cars regularly average more than 65mpg. On paper, at least.

Low CO2 emissions go hand in hand with good fuel economy, so there is a double bonus to buying an economical car – you'll pay less in tax. Both road fund licence and company car tax are based on CO2 emissions: the lower they are, the less you pay.

So which are the most economical cars in Britain? MSN Cars is committed to bringing you details of the cars with the best fuel economy on sale in the UK. This is our guide to the most efficient and cheapest new cars money can buy.

We have gathered all the free road tax diesel and petrol cars on sale in Britain here, to show you just how broad and far-reaching the low-emissions choice now is in the UK.

Buy many of the cars here and you’ll even be able to drive into Central London for free: the cars emitting less than 75g/km of CO2 are so green, they are exempt from the Congestion Charge.

Read on to discover the most economical new cars on sale. You'll save a fortune on your fuel bills by choosing one of these fuel misers!

How to avoid London's Congestion Charge: the cars exempt from new 75g/km limit


1. Vauxhall Ampera/Chevrolet Volt - 27g/km

The current European Car of the Year is the Chevrolet Volt and Vauxhall Ampera - and with economy this good, it's easy to see why.

Thanks to an ingenuous combination of electric-drive and petrol-powered electricity generator for when the circa-40 mile range is exhausted, they give EV motoring without the range restrictions, and a staggering official combined economy figure of 235.4mpg.

2. Toyota Prius Plug-in - 49g/km

The Toyota Prius Plug-in is just that - a regular Toyota Prius with additional batteries that can be charged by 'plugging them in' to the mains electricity supply.

Because they can store more electricity, they allow an all-electric range of up to 15 miles before the petrol engine kicks in. Thanks to this, the official combined consumption figure shoots up, to 134.5mpg.

3. Fisker Karma – 53g/km, 62.4mpg

Fisker Karma

The Fisker Karma combines two unlikely bedfellows – jaw dropping good looks and tree-hugging emissions. Designed by Henrik Fisker – who had a hand in penning the Aston Martin DB9 – the Karma is a series hybrid which employs a 2.0-litre turbo engine as a generator to re-charge its lithium-ion battery pack.

With a powertrain that produces 397hp it isn’t slow – 0-60mph taking just 6.3 seconds. A claimed 62.4mpg and emissions of just 53g/km make this one guilt-free luxury saloon.

4. Toyota Yaris Hybrid – 79g/km, 80.7mpg

Toyota Yaris Hybrid (© Toyota)

Toyota has smartly combined the 1.5-litre engine and electric motor drivetrain of the Prius and Auris HSD with the lighter and more compact body of the Yaris. Result? The Yaris Hybrid.

Because it's so much lighter than its bigger siblings, it's even more fuel-efficient, averaging up to 81mpg and emitting just 79g/km CO2 - Toyota's lowest-ever figure. It can even travel for around a mile using electric power alone.

5. Renault Clio 1.5 dCi 90 ECO – 83g/km, 88.3mpg

Renault Clio

Eco by name, eco by nature – the newest version of Nicole’s runabout has a 1.5-litre diesel engine that’s capable of 88.3mpg and puffs out just 83g/km CO2.

Wrapped in the brand new Clio’s clothes it’s a stylish and contemporary option for the budget-conscious supermini buyer. It also trumps the VW Polo BlueMotion and Ford Fiesta ECOnetic when it comes to green credentials.

6. Hyundai i20 1.1 CRDi Blue – 84g/km, 88.3mpg

Hyundai has recently facelifted the i20 supermini and part of the revisions include the launch of a super-efficient diesel model, using the firm's excellent 1.1-litre three-cylinder engine.

In eco-orientated Blue trim, it emits just 84g/km and averages an impressive 88.3mpg. Combined with great value prices, Hyundai has a compelling deal - the greenest regular-engine road car, for one of the best-value prices on the road.

7. Kia Rio 1.1 Ecodynamics - 85g/km, 88.3mpg

The roomy and practical Kia Rio five-door, five-seat supermini is a star when it comes to economy. With 88.3mpg and 85g/km CO2, Kia said it was the most economical conventional-engine car on sale anywhere in the world at launch.

Well, it was until Hyundai rolled out the i20 sister car with CO2 emissions that beat it - by 1g/km...

The Smart Fortwo cdi diesel's long reign as most economical car on sale in Britain is over. Despite this, it still averages an impressive 85.6mpg.

It only seats two, and the clattery diesel engine is not the fastest or most refined on sale. It is still economical enough to only now have been unseated as the UK's most fuel-efficient car, though.

With the 208, Peugeot has made its prettiest supermini since the classic 205. But it's not just a pretty face: the super-efficient 1.4-litre e-HDi engine is also very fuel-efficient too.

It is capable of returning up to 83.1mpg and emits just 87g/km, with a clever and seamless stop-start system cutting inner city exhaust emissions too. The new top dog in the supermini sector?

9= Citroen C3 1.4 e-HDi 70 Airdream EGS – 87g/km, 83.1mpg

Not to be outdone by its parent firm Peugeot, Citroen has also made its most fuel-efficient supermini yet. The Citroen C3 in 2012 Airdream guise emits just 87g/km CO2.

This equates to diesel fuel economy of 83.1mpg, with all the easy-driving advantages of EGS automatic gearshifts too. As Citroen dealers love to do a deal, it's a green supermini that's well worth checking out.

11. Lexus CT200h S – 87g/km

Lexus CT200h

Bringing hybrid power to the premium compact sector is the petrol-electric Lexus CT200h’s raison d’etre. The appeal of this car lies in the marriage of smooth hybrid drive powertrain and the lure of fantastic Lexus customer service. Oh, and astonishing economy.

Thanks to smaller wheels and a larger spoiler than the standard CT200h, the S model emits just 87g/km of CO2 and manages a pretty startling 76.3mpg. Low benefit-in-kind company car tax liability and road tax exemption, are the icing on the cake for this premium eco choice.

12. Vauxhall Corsa 1.3 CDTi 95 EcoFlex S/S – 88g/km

The Vauxhall Corsa is one of the nation’s best selling cars and the range extremely large and varied.

It keeps on getting greener with every passing month too. Right now, it can be bought with stop-start which, on the punchy 95hp 1.3-litre diesel, provides 88g/km CO2 emissions and average fuel economy of 85.6mpg.

Renault has always known how to build competitive diesel cars: the facelifted 2012 Megane shows it's at the top of its game, with average fuel economy of 80.7mpg.

This is achieved without resorting to expensive electric-assist drivetrains or pricey bodywork additions. That all Megane dCi 110 Stop and Start models return such impressive fuel economy really is a top result for Renault.

16= Fiat Punto 1.3 MultiJet 85 – 90g/km

Fiat Punto

The 1.3-litre MultiJet diesel unit in the Punto is arguably the pick of the range –refined and torquey, it provides excellent in-gear grunt. The Punto’s eco-credentials are strong, too – 80.7mpg and CO2 output of 90g/km.

The Punto is a spacious and economical choice – if not at the top of the class dynamically speaking.

Volkswagen's mini-Golf Polo is offered in green-focused BlueMotion guise, using the same 1.2 TDI diesel engine as the Skoda.

Citroen’s stylish DS5 is something of a return to form for the French maker. Stylish and individual – it makes a strong case for itself when combined with the 200hp Hybrid4 diesel-electric powertrain.

The Peugeot 3008 Hybrid4 mates a 2.0-litre diesel HDi engine with a rear axle electric motor, creating the world’s first diesel hybrid.

It works well on paper, with recent updates cutting it further: the base car with smaller wheels now emits just 91g/km CO2. Pity it doesn’t perform quite as well in the real world…

SEAT's VW Polo-based Ibiza returns the same 80.7mpg as the VW - the smallest of differences account for the extra 1g/km CO2.

The stylish Volvo C30 DRIVe was one of the first 'super-eco' cars on sale. Volvo refreshed the diesel engine for 2011 - it now produces 115hp.

I wish you lazy motoring journos would get in and test the damn cars you write so positively about!. I bought a Fiat Twinair on the strength of these sorts of reviews a year ago. I have never got it to do more than 50.5 mpg combined and I drive very carefully. So carefully that my colleagues findit funny, that's how carefully.

DON'T BELIEVE THE HYPE, PEOPLE.

Running costs go much further than fuel economy, for example I find it far more cost effective to run an older car (astrq 1.7td) which although isnt as economical as newer cars, the fact that I have no finance on it makes running costs much lower than having a new car on finance. The fact that the astra has no street cred doesnt bother me, but it has now done 205k miles and has only one not started due to the (original) battery being killed off by last winter, no great shame there......... Still does 55mpg too.

 

I'm no luddite, I know the world has moved on, and if I had the money to buy a new economical car....... I'd still keep the astra, buy something interesting for nice days, and keep using the astra day to day.

 

, I'm paying my house off much faster...........

I understood there was a problem with the manufacture and disposal of the Toyota Prius Batteries ? All very economical just not very eco friendly. So what exactly is it we are expected to be doing - Economical or Eco friendly ?

A friend of mine  bought a Toyata IQ   under  the government  scrapage scheme on the basis that the IQ did over 70 mpg .   The diesel car he scrapped did 55mpg .He is lucky if he gets 44mpg out of the IQ
The garage has been really skillful in putting him off , like you have to run in more miles. well after 10,000 miles it is still no better.
What it needs is for all owners of new cars that do not  get the advertised mileage to complain to trading standards, and or a class action in the courts against a manufacturer. .
If enough people do it , then they will change the way they test new cars  and stop  misleading selling  on  imaginary  unachievable mileage figures.

Bought a 94 Rover 214sei previous January for £370 including five months tax and eight months mot. Clean and tidy car with reasonable power and economy. Running costs in past year - front brake pads for £18, part worn tyre £15, 40 quids worth of welding for mot. Plus cheap road tax and insurance. Still going strong 7,000 miles after purchase. That's what I call economy. If it terminally junks, I'll get £100-£120 from scrappy!

I drive a Fiesta Econetic 2011 model, it only averages 63mpg, I did get it to 66mpg at one time, but then it didn't keep to that figure, so 78mpg is just pie in the sky, it might get that figure on a bench but not in real life driving, which is what should be used not a bench test.

The problem is with diesel/petrol that, although diesel is cheaper to produce that petrol, the tax on it is a lot higher, so that it costs more.  This needs to be taken into account when comparing running costs. Not just the m.p.g.

So where's the Fiat Panda JTD (or F500, similar)? They have the exact same engine as in the Corsa. My dad's had one for a couple years now and, having never reset the trip computer, has a "lifetime" average of 68mpg over a wide variety of use. This in a previous generation model, which cost about 7 grand brand new. I can't see the current one not making the list if they've given it the same updates as the Punto & etc.

Also, "Top 10 most economical"? With a long list of joint 11ths and joint 13ths, some with noticably different MPG figures? Did you actually mean "Top 20 low-CO2 cars" or "Top 20 cars under 100g/km CO2"? I mean, it's an impressive list - there's now a lot fewer practical reasons NOT to buy something with such low emissions it gets free road tax (...for now), never mind the EU target of 120g average... but it's not entirely "most economical" is it?

I do wonder, finally, what the deal with all those different cars having 74.3mpg is. Is there some kind of euro directive that has similar tax breaks to our zero-road-fund-license thing which is pegged at 3.8L/100km or lower fuel consumption? (That's what the suspiciously precise 74.3 works out to... like a tenth of an MPG makes any realistic difference when your economy is that good, even with fuel so expensive? Hit a bad headwind and you lose 2-3 MPG anyway, never mind 0.2)

Let's see if anyone makes the mental leap of putting a small multiair-ish diesel as the powerplant in a plug-in hybrid with a slightly larger battery (maybe not to Chevy Volt / Vaux Ampera levels, but good for maybe 15ish miles at faster citybound speeds) and see the figures really tumble. Sub-80g/km and 100+ mpg equivalent in a Golf-class vehicle with decent (~1.4L previous gen petrol) performance would be doable for not much more money than these lot cost, not to mention pretty amazing.

You are doing well Top Gear got the MPG down to an average of 30 mpg Yes that's right THIRTY MPG you see the motor companies use a rolling road and a simulation on a laptop to make the test repeatable on all cars so that comparisons can be made without too many variations this means that wind resistance does not seem to be taken into account

The vauxhall courser and new ford KA are also under achievers

Official mpg figures given by motor manufacturers are misleading. They do not come anywhere near the stated figures. Why has the office of fair trading not got involved. Car makers can quote what they like so why are they getting away with it.

I own a 1.5 dci 2001 Clio, it easily averages 65mpg without trying. This is by far the best car I have ever owned and I would highly recommend it. Mine has now done 140k and is still running smooth and with only £30 a year road tax and low insurance it really is cheap in every way. I've recently had a company car with one of the new Eco petrol engines and they are a complete joke, struggling to average 30mpg when really trying. Always stick with diesel for Eco in my opinion!!

Republishing an old article without doing your homework.  Poor effort MSN.  The latest Fiesta has a claimed 85.6MPG and produces 87gms of CO2, so should've made the top ten.  Obviously those figures remain unacheivable in the real world, but that doesn't stop any of the other manufacturers claiming equally fantastical numbers.

The most economical car I have owned was an Audi A2 1.4TDI

Bought a Astra 1.7cdti (125) and poor mpg a big problem I find is a.. the on board computer is always 4 to 7 mpg incorrect as you think you are doing well but only way is brim fill it up and work out mpg over miles yourself.

b... The car makers give you extra gears i.e 6th so that you can run at faster speeds at lower rpm to give better mpg but if you drive keeping revs under 2000 you seem to fill this diesel particulate filter filling up and it goes onto a cleaning recycle knocking the fuel consuption down, this happens every other week,  I drive the car normaly over 4 weeks 4 fill ups 750 miles ave 43.9 my rover 45 2.0 was getting 50+ mpg doing same speeds and roads etc, the overall mpg on this model says 62 mpg and these figures are no were near to true mpg

citroen c1 scores well compared to the cheaper suzuki alto road tax is £20 a year for both and insurance is cheaper for me in the citroen than the suzuki alto the mpg is about the same for both but the citroen has a better build quality as it is a toyota aygo in disguise they are both  city cars but the suzuki has a bit more room thay are capable on the motorway the citroen can be a bit sluggish on hills with more than one occupant  and both cars are a bit short on boot space so a split fold rear seat may prove its worth.

 the only problem occasionally reported in the citroen being a stiff clutch

incidentally the suzuki alto interior plastics are poor the engine mounts can become noisy and the rear wash  tube regularly detaches from the pump resulting in a wet foot (the alto is made in india and to a price) The citroen is made in the czek republic again to a price

I hope this helps in your decision when buying your next petrol sipper

Fisker Karma lovely, fast .economical, modern and the inside is amazing.
Ok so those are the upsides now for the downsides 0  thats Zero UK dealers nearest one is in France and a UK price conversion of £87.000 to buy means you will have to be very light footed indeed to make the money back. Not so economical then.

I am loving my Ampera.
I know it is not cheap to buy and I know it is not the complete answer yet. Nevertheless, I would be buying a car in the £30k price bracket anyway and the bonus is that the Ampera just happens to deliver about 50 miles of electric driving for £1, before switching to petrol.
It is also well equipped, smooth, quiet and yet surprisingly quick.

I just got a Vauxhall Corsa 1.3 diesel ecoflex as it should get better economy and should save me as much in fuel as it costs on finance, plus being a new car is less likely to break down on my 120mile round trip to work every day.

However, I haven't been able to get it above 50mpg so it is not saving me any money and is in fact costing more when the finance cost is added!! It is also less comfortable, and considering that my previous car was a Honda Civic, 2003, petrol! I still wish that I had kept this car. My Honda had over 160K on the clock and still managed about 40mpg - which was increasing slightly since I changed the oil! Therefore, i wish I had kept the old car!!! (Plus the gearstick was in a much better position, very roomy and lots of floor space!)
