Cadillac's rival to the BMW 3 Series dead after just six years on sale

The Cadillac ATS sedan looks set to be discontinued after this year, just six years after being introduced as a competitor to the BMW 3 Series and Mercedes-Benz C-Class.

Speaking with industry journal Automotive News, Cadillac spokesperson, Donny Nordlicht, said: "Production of the ATS sedan is ending due to extensive plant upgrades, expansion and re-tooling to prepare for the next generation of Cadillac sedans".

"Cadillac's future sedan portfolio will consist of three sedans, positioned in different segments and and clearly differentiated by size and price."

According to the report, the roles currently occupied by the ATS, CTS and XTS will be taken over by two new sedans, though timing for these new models is yet to be announced.

Meanwhile, the CT6 will remain Cadillac's sedan flagship, serving as technology showcase. This year, the CT6 will introduce the company's Super Cruise semi-autonomous driving systems.

Despite the discontinuation of the ATS sedan, Cadillac has confirmed it will continue production of the ATS coupe (pictured in black) for the 2019 model year.

In 2017, sales of the ATS fell by 39 per cent, though so far in 2018 the small sedan has risen by 7.4 per cent.

The ATS sedan may be on the chopping block, but GM's luxury division is plotting a serious model onslaught over the next three years.

Starting with the new XT4 SUV later this year, Cadillac has confirmed its plans to launch a new model every six months through to the end of 2021.

After the XT4, Automotive News speculates the XT6 – a new three-row SUV – will be the next new offering to be launched under the Cadillac brand.
