%VIRTUAL-SkimlinksPromo%The price of supermarket fuel is to fall, providing motorists with some good mid-winter news.
Asda and Tesco are both reducing their petrol and diesel prices by up to 2p a litre from tomorrow.
Asda, the first to announce a cut, said that from tomorrow motorists would pay no more than 126.7p a litre for petrol and 133.7p a litre for diesel. It added that its diesel would now fall to its lowest price since July 2012.
AA president Edmund King said: "Fuel price reductions at the pumps will bring a sigh of relief to many drivers who are struggling to make ends meet after bigger than normal financial outgoings during the festive period.
"We hope that other supermarkets and fuel retailers follow the lead of Asda and Tesco to cut their prices at the pumps otherwise we just end up with a fuel-price lottery based on proximity to certain supermarkets."
RAC external affairs head Pete Williams welcomed the reductions and said that if they were matched around the country prices would fall to their lowest since February 2011.
He went on: "This will no doubt have a positive effect on the economy too as well as lessening the social impact that high fuel prices have on people's personal lives."
The most economical cars to run
Supermarket fuel price cuts hailed
Official mpg: 57.6mpg True mpg: 45.4mpg
The third generation Seat Leon is the most economical car to run according to the WhatCar? True mpg test.
It's been a good year for the Spanish manufacturer as the Leon also won the Auto Express New Car Award 2013 after years of missing out to sister brands Volkswagon and Skoda.
The 1.2 TSI 105 has the smallest engine of the top six cars in the WhatCar? lineup, so unsurprisingly is the most efficient of the group.
As well as being efficient it's a great family car. You get plenty of cabin space and an impressive boot size of 380 litres - 65 litres more than in a Ford Focus!
The cheapest in the range is the 1.2 S-trim, but even as a starter model you get a decent standard of equipment with things like air-conditioning, Bluetooth, 5" colour multimedia screen and tyre-pressure monitoring included.
You can buy a new Seat Leon 1.2 TSI 105 S 5-door from £15,850.
Official mpg: 55.4mpg True mpg: 42.8mpg
The stylish Mazda 3 is second on the list of the most economical family cars to run. And like the Seat you can get a starter model relatively cheaply, but with a generous helping of the best mod cons.
The entry-level SE models come with alloy wheels, Bluetooth and air-conditioning as standard. Plus, in terms of size, the 3 is almost on par with the Seat Leon.
WhatCar? says it's a fun car to drive and although it misses out on the top spot for fuel economy, it's not far off so worth a look.
The 2.0 Skyactiv-G 120 5-door is available from £16,995.
Official mpg: 54.3mpg True mpg: 42.5mpg
The Audi A3 was named Car of the Year 2013 by WhatCar?, but only manages third place on its list of the most economical family cars to run.
It's not the cheapest motor, but the A3 offers plenty of space with a boot size of 380 litres on the Sportback. That's perfect for a family with a lot of gear to transport.
WhatCar? says it should definitely make the shortlist if you are looking for a decent sized hatchback.
The Audi A3 Sportback 1.4 TFSI 122 5-door can be purchased from £20,200
Official mpg: 52.3mpg True mpg: 42.1mpg
The Kia Ceed provides an exceptional amount of space (1,318 litres with the seats down) and comfortably transports five adults.
Its large 1.6 engine can almost match the economy of rivals, but WhatCar? says the petrol version of this car is a disappointment compared to the diesel in terms of driver enjoyment.
The Kia Ceed is available in four trim levels. Top level Ceed '4' gets you parallel park assist system (PPAS) which automatically parks your car! But your basic trim '2' isn't exactly rubbish with reverse parking sensors included.
The Kia Ceed '2' 1.6 GDi 133 5-door is available from £16,195 and comes with the Kia seven-year warranty.
Official mpg: 51.4mpg True mpg: 41.5mpg
The new A-Class looks pretty great with its sharp exterior and smart cabin, and the A180 has attracted high praise from the likes of Top Gear magazine who claim it's enough to rival the BMW1-Series and the Audi A3.
But WhatCar? says that even though safety and equipment levels are up there with the best (you get alloy wheels, Bluetooth and air-conditioning as standard with every model) it's a disappointment to drive.
If you want to be the judge, the A180 is the cheapest Benz you can buy. You can get the A180 BlueEfficiency 122 five-door from £20,370.
It's not the most stylish motor of the lineup but WhatCar? reports that the petrol engines are smooth and quiet, while the cabin is a comfortable and spacious place to sit - six-foot adults can sit comfoirtably behind similar-sized adults at the front with leg-room to spare!
If you fancy it the 1.4 TSI 140 is available from £18,390.
