BERLIN (Bloomberg) -- Audi will spend 24 billion euros ($29 billion) to develop technology and expand production, boosting its five-year investment plan by 2 billion euros ($2.44 billion) as it chases BMW for the top spot in luxury-car sales.
Audi expects to sell a record of more than 1.7 million autos this year.
"We are making large investments in the innovative areas of electric mobility, connectivity and lightweight construction," Audi CEO Rupert Stadler said in the statement.
Audi intends to increase its lineup to 60 models or variants by 2020 from 50. Audi, the No. 2 brand in global luxury-car sales, aims to surpass BMW in deliveries by the end of the decade. The race tightened this year. BMW outsold Audi by just 42,600 cars in the first 11 months of 2014 compared with 54,600 a year earlier.
Audi's budget is part of Volkswagen's 85.6 billion-euro investment program to beat Toyota Motor Corp. in global auto-industry sales.
Audi plans to spend the equivalent of 4.8 billion euros a year, an increase from the previous rolling five-year plan that called for investing 4.4 billion euros annually on new vehicles and expanding production capacity.
"Despite the growth in total investment, we will keep a watchful eye on the upcoming challenges and exercise the required cost discipline," CFO Axel Strotbek said.
Audi, which already outsells BMW in China and Europe, is aiming to catch up in the U.S.
In November, it unveiled the Prologue concept car at the Los Angeles auto show to showcase a more aggressive design.
The company also plans an electric crossover for the U.S. in 2017 to challenge Tesla Motors Inc. and is building a factory in Mexico that will start building the Q5 SUV in 2016 for America.
Audi said on Saturday it will hire another 850 workers at the Mexico plant next year.
BMW is seeking to fend off Audi and Mercedes-Benz, which also covets the top spot, with its own expansion, adding cars like the X4 coupe-like SUV and the i8 plug-in hybrid supercar.
Under its previous budget drawn up a year ago, Audi announced investments of 22 billion euros over the 2014-2018 period. Parent VW in November unveiled auto investments of 85.6 billion euros through 2019, slightly more than a year earlier, even as the carmaker is pushing cost cuts at its core brand.
