Audi will kick off one of the most aggressive two-year model expansions in the luxury-car industry at the Detroit motor show as the German marque closes in on BMW, which sold a record of more than 2 million cars last year.

After narrowing No. 1 BMW AG’s lead further last year, Audi will target buyers of big cars in Detroit with a revamped version of the Q7, its $48,300 sport-utility vehicle. Still to come later this year is Audi’s first electric sports car for aficionados of technology and speed.

“The most impressive launch schedule in the coming two years will most likely be at Audi,” Jochen Gehrke, a Frankfurt-based analyst for Deutsche Bank, said in a note.

Audi plans to spend 24 billion euros ($28.3 billion) on technology and production in the next five years, with most of the money going to expand its lineup to 60 cars from 50. Audi’s goal is to wrest the No. 1 spot in the luxury-car market away from BMW by 2020, in a three-way race that also includes Mercedes-Benz, which has declared the same ambition.

Including Mini and Rolls-Royce vehicles, BMW delivered a record 2.12 million cars last year, a gain of 7.9 percent. Growth was paced by a 9.5 percent gain at the namesake brand to 1.81 million cars. With Audi growing 11 percent and posting a new sales record of 1.74 million autos, BMW’s lead over Audi narrowed to 70,619 from 79,658 a year ago.
