New cars not giving drivers advertised mpg

New cars not giving drivers advertised mpg 27th April 2015

When buying a brand new car, most of us would expect that one of the main benefits of doing so would be the fact we would be driving a more efficient vehicle. Spending less on fuel per year can make a big difference to drivers, and helps to offset the cost of purchasing the new vehicle. 

However, consumer watchdog Which? has claimed that many drivers who purchase new vehicles are not getting the miles per gallon (mpg) rating that is advertised by manufacturers, and could be spending more than they intended to as a result. 

The watchdog tested some 200 vehicles available in the UK to see if they were as efficient as they claimed. Shockingly, only three of the models that it put under scrutiny met their official fuel economy level. 

On average, it said, vehicles fell 13 per cent short of the advertised levels. For drivers who are undertaking journeys amounting to 10,000 miles per year, this could mean paying as much as £133 more for their fuel. 

According to the SMMT findings, the worst vehicle for fuel economy compared to advertised levels was the Mitsubishi Outlander PHEV hybrid. Despite an official advertised efficiency level of 148mpg, Which? was able to get only 67 miles to the gallon from it. 

Fuel efficiency is a concern for all drivers, and for those struggling to get the desired efficiency from their new car, there are a number of different ways to make sure that you can improve it. 

One of the most common contributing factors to fuel efficiency, making sure your tyres are properly inflated will make a big difference. Michelin says that not having tyres properly inflated will lead to an increased rolling resistance, which can cause the car to use up to six per cent more fuel. 

To help mitigate against this, you should always make sure to check your tyre pressure once a month. If they always seem to be deflating, they may have a slow puncture, in which case it can be best to have new tyres fitted

Other ways to improve fuel efficiency include making sure you are not carrying unnecessary weight in the vehicle, and ensuring that you have the engine serviced and tuned to make sure it is performing to the best of its ability.
