What are the running costs?

In terms of fuel efficiency, all Sandero Stepway models are reasonably economical. According to the official WLTP figures, the LPG Bi-fuel TCe 100 model is the least economical, especially when running on LPG when it’s only able to manage around 40mpg. This goes up to nearly 50mpg officially when running on petrol, but LPG is much cheaper so worth using if you’re able.

Most economical is actually the most powerful TCe 110 model, which claims 51.5mpg WLTP. But the TCe 90 is only slight behind this figure with the manual gearbox, falling to 45.6mpg with the automatic transmission.

The good news is that we were easily capable of matching the claims in our extended long-term test of the Dacia Sandero Stepway. Over the course of several months, we managed an overall average of 47mpg.

Servicing and warranty

The Sandero Stepway comes with an industry standard three-year/60,000-mile warranty. Dacia also offers a configurable extended warranty that can last for up to six years or 100,000 miles.

Dacia recommends yearly services and offers service plans with courtesy car options and waiting appointments.

Reliability

  • Powered by existing well-proven engines
  • Lots of shared technology with other Renaults
  • Dacia has a reasonable reliability record

Dacia generally scores slightly higher than average in customer satisfaction surveys, but our Sandero Stepway owners’ reviews point to a few faults concerning the electrics.
