Infiniti has confirmed it will launch its Q30 lower medium vehicle at the Frankfurt motor show in September with UK sales starting before the end of the 2015.

Infiniti debuted the Q30 concept car at the 2013 Frankfurt motor show. Nissan’s premium arm said it is currently testing the vehicle in the UK.

Infiniti has not said what will power the Q30 or how much it will cost.

Speaking to BusinessCar in April, Infiniti’s UK regional director said that a new small SUV will be built on the Q30’s platform.

Carl Bayliss also said Infiniti is making progress on introducing more diesel technology into its products.

He said: “Traditionally, we’ve had quite a US-centric powertrain strategy, but we’ve got the 2.2-litre diesel and we’re getting more of a global focus with what’s coming now.”

Bayliss said that while nothing was confirmed, the firm is looking at introducing a smaller-capacity diesel with improved efficiency figures in the future.

Infiniti’s current 2.2-litre diesel offers CO2 of 114g/km in the Q50 saloon. While that’s not bad, the firm will need lower-CO2 engines to compete on a whole-life costs basis with premium competitors

There are a “couple of people” working on Infiniti’s fleet sales in the UK, but the onus will be on being driven by those user choosers who are intrigued by something different. It’s described as a pull strategy, rather than push.

Bayliss said: “We’re building our fleet business on a local level with SMEs.”

He added that it was possible the Renault-Nissan group’s fleet teams could collaborate in the background to introduce Infiniti as a premium offering when talking with larger fleet clients.

However, he said that while cross-brand deals have happened in Europe, it was “still under consideration” for the UK.
