Diesel cars make up around 50 percent of new car sales in the UK, but it wasn't always that way.
In fact, it was only in the mid-1990s when Volkswagen, Peugeot and others started offering diesels with improved refinement, performance and economy that the buying public really took them to heart - and with the average petrol family car getting little more than 30 mpg, diesel looked even more attractive.
With higher diesel prices and higher pricetags the decision is no longer so clear-cut, particularly when companies like Audi are offering such fuel-efficient petrol cars.
The new A3 1.2 TFSI puts out 105 PS and gets to 62 mph in a shade over ten seconds - similar to the company's 1.6 TDI.
It's cheaper to buy than the diesel though, which starts at 20,155 in equivalent SE trim - and while the 1.6 manages a highly impressive 74.3 mpg, the petrol's 57.6 mpg combined economy is nothing to sniff at.
Take into account the extra price of diesel and a little number-shuffling with real-world economy, and the running costs could be pretty close - even before you factor in the extra few grand in list price for the DERV-drinker.
You'll pay a little more in road tax, though - the diesel sneaks in with 99 g/km (also gaining congestion charge exemption in London), though 114 g/km in the 1.2 will hardly break the bank.
A lighter body than the previous 1.2 TFSI A3, an improved injection system, better turbocharging technology and a start-stop system all contribute to the TFSI's impressive economy figures.
Equipment levels are also strong in all three trim levels, SE, Sport and S line. Alloy wheels, Bluetooth and air conditioning or climate control are all standard, while Sport and S line models get larger alloy wheels, sport seats and more.
