Buick's new electric concept car combats road rage with aromatherapy and massaging seats

Buick's first electric car goes on sale in 2024. The Wildcat concept previews what the iconic American brand has in store.

• Buick revealed an electric concept car with some wild features — meet the Wildcat. 
• The car can sense an elevated heart rate and calm down its driver. 
• The Wildcat is just a design exercise. Buick's first real electric car will hit the market in 2024. 

Buick, General Motors' century-old brand, said Wednesday that it plans to only sell electric vehicles by the end of the decade.

It unveiled a sleek electric concept car to illustrate the new direction.

The Wildcat doesn't just preview what future Buicks could look like, it also showcases some experimental features that could make their way into the brand's electric models.

The two-door EV debuts Buick's new logo.

The coupe has a low, wide stance and four seats.

Part of its roof opens up to make getting in and out a bit easier.

The Wildcat has big, bold, checkmark-shaped taillights...

... that mirror a similar design up front.

The entire vehicle has exaggerated, aggressive looks.

Its turbine wheels take inspiration from the Jet-Age cars of the 1950s and 1960s.

In place of regular side-view mirrors, the Wildcat concept has cameras and small screens.

The interior gives off spaceship vibes, but has some elements that could end up in actual production Buicks — like a giant, curved screen.

Other parts of the Wildcat are hard to imagine in a real car. For example: it's designed to detect a driver's mood and react.

Say a fellow motorist just cut you off or won't stop honking. If the Wildcat senses an elevated heart rate, it will dim the lights, switch on massaging seats, and deploy its integrated aromatherapy functions.

Buick's future electric models will be sold under a new Electra brand, the company said on Wednesday.

Its first electric model in North America is set to go on sale in 2024.
