  • Diesel the cheapest to run – for now
  • Not much difference between 115-150hp models
  • Petrol model only marginally worse

As always the cheapest fossil fuel Octavia to run is the lowest-powered diesel, with 115hp. This boasts between 57.7 and 67.3mpg and 111-127g/km of CO2.

Our favourite all-rounder is the more powerful 150hp diesel, which claims a marginally worse 57.7-65.7mpg and 112-129g/km of CO2 despite its additional power.

Adblue tank capacity for this diesel Octavia is 13.35 litres.

The best performing petrol is the 110hp 1.0-litre, with figures of 46.3-54.3mpg and 117-138g/km of CO2. We suspect it'll take a long motorway cruise to gently work your way up to those fuel figures, as this engine may need to work harder to get the Octavia up to speed elsewhere.

There is a mild-hybrid e-TEC version of this engine, which only comes with the automatic DSG gearbox and uses a clever 48-volt electronics system to feature an enhanced stop-start system to save even more fuel and give a small boost in performance. The on-paper figures of 44.8-56.5mpg with CO2 output at 115-143g/km might not seem much at all, but this system will make more of a difference in towns and cities with heavy traffic.

Plug-in hybrid iV model is best on paper

If your lifestyle supports it – off-street parking with access to charging and daily short journeys – then the iV excels. You might even see the clamed 188.3-256.8mpg if you make good use of the 43-mile range.

Business users will also benefit from a 6% BiK rate thanks to that range and the 24-33g/km CO2 the Octavia iV is capable of producing.

However, anything less than that will see the fuel economy drop, but even so you should get 55mpg at the very least. In cold weather you can expect the maximum electric range to drop too.

vRS models are a mixed bag

On the one hand you have the 2.0-litre TSI DSG model with a claimed economy of 35.3-40.4mpg and 159-181g/km of CO2, but on the other there's a cheaper-to-run diesel and plug-in hybrid version.

This TSI petrol is also available with a manual gearbox, which achieves a slightly better 36.2-40.4mpg and emits a slightly lower 159-177g/km of CO2.

The diesel claims to achieve between 52.3-55.4mpg, with CO2 output of 132-142g/km. We achieved between 43.8-45mpg with this vRS TDI during our time of testing, over a mixture of motorway and country roads. If you opt for the 4x4 version, the mpg figures drop down to 45.6-50.4mpg, with CO2 rising up to 147-162g/km.

We'll know more about the hybrid when we've driven it, but can safely say you'll need to keep the hybrid battery charged up as often as possible to achieve near the 176.6-235.4mpg figure. The CO2 output also makes this the cleanest vRS, ranging between 27-36g/km.

Reliability

  • Hard to judge this new car
  • Lots of shared tech
  • Newer engines used elsewhere

This updated Skoda Octavia is still a little too new to pass judgement on in the reliability department, but if previous generations are anything to go by you should have little to worry about.

Although relatively new in some respects, most of the engine tech used here is proven and used widely throughout the VW Group, although the mild hybrid units feature some fancy electronics.

A lot more of the controls in the interior have been given over to the infotainment screen and while that may be an ergonomic concern, there’s nothing to suggest this should be any more fragile than the old car’s manual buttons and switches.
