The XT4 will go on sale in the US in the autumn, with prices starting at $35,790 (£25,500).
It will be powered by a 2.0-litre turbocharged petrol engine that produces 234bhp and up to 258lb ft of torque, and features a nine-speed automatic gearbox and optional all-wheel drive. Cadillac estimates a combined 32.4 UK mpg.
Cadillac is owned by General Motors, which last year sold its largest UK brand, Vauxhall, to the PSA Group. Cadillac has previously focused on large saloons and SUVs, and company bosses believe the XT4 could appeal far more to European buyers. The firm currently has just two official UK dealers.
The five-seater is 4599mm long, 1881mm wide and 1627mm high, with a wheelbase of 2779mm. It features MacPherson strut suspension at the front, with five-link independent struts at the rear. Active sport suspension will be available as an option.
