Tata Motors' Jaguar will launch new affordable models from 2015 in a bid to emulate the success of lower cost luxury vehicles made by its sister company Land Rover, Reuters reported, citing two sources close to the company.

The new cars will include a compact saloon and crossover SUV - currently the fastest-growing models in terms of global sales - and be available in the second half of 2015.

Jaguar said last year a smaller model and an SUV were among a number of possibilities being looked at by the brand. Such vehicles will provide direct competition to similar cars from BMW and Mercedes-Benz.

The Range Rover Evoque small SUV and Land Rover Freelander are currently among JLR's top selling models.

JLR sales rose 14% in the first half of this year to 210,190 cars, helped by fast-growing China – although Jaguar models accounted for less than 20% of the total.

Since being acquired by Tata from Ford, JLR has gone from strength to strength helped by the growing demand for luxury cars in emerging markets. With Land Rover sales in particular booming, Tata bosses are keen to bring Jaguar up to speed.

Reuters’ sources said a new family of more affordable Jaguars will be built on production lines previously used to make Land Rover vehicles. The new range is likely to be all-aluminium, as used for the recent Jaguar XJ. JLR last year signed a deal with a Saudi Arabian firm to buy aluminium from one of the world's largest smelters in the kingdom.

JLR said earlier this year it planned to invest GBP2.7bn (US$4.2bn) each year for the next four years on new products and production facilities.
