New Volvo V40 and XC40 concept teasers

The all-new Volvo V40 and XC40 are believed to have been officially pictured for the second time in teasers released on Snapchat - although Volvo hasn't confirmed any details of the cars beyond hinting that they belong to the brand's smallest family of models, the '40 series'. 

Volvo has revealed its new concepts. View the V40 concept here, and the XC40 concept here.

A Volvo spokesperson could not specify what type of car the concepts would be when contacted by Autocar, but it is known that Volvo will reveal two separate concept cars this week. It was also confirmed that the two cars will sit on the all-new CMA platform, which has been co-developed with Volvo owner Geely and will underpin Volvo's smallest model range. CMA is designed to be premium enough to allow Geely to develop more upmarket products while supporting a more profitable, wider range of Volvo’s 40 series models.

Unusually, Volvo used the social network Snapchat to tease the pictures, which is believed to reflect the company's desire to attract younger buyers with its smaller, cheaper models. The caption on one of the images reads "Not your daddy's Volvo", again hinting that it will appeal to younger buyers.

The images also confirm that the concepts will closely follow Volvo's current design conventions, with 'Thor's Hammer' LED daytime running lights set in intricate light clusters and uncomplicated front-end styling.

The next-generation Volvo V40 and XC40 will be powered by a mixture of three and four-cylinder engines, with plug-in hybrid and potentially fully electric versions of the cars also being developed.

The Volvo XC40 is strongly tipped to be the first model in the range to be launched, most likely in 2017, because of the sales potential of small crossovers in the current booming market. Insiders believe the Infiniti QX30 and Mercedes GLA rival could end up being the firm's best-selling model.

A Volkswagen Golf-rivalling V40 hatchback and a small Volvo S40 saloon, which will be in effect a rival for the Audi A3 saloon and the BMW 2 Series saloon, will then follow.
