The diminutive EVs are the first production-bound Daimler vehicles to wear the new 'EQ' branding.
The pair of special-edition smart EVs will be the first series-produced models to feature EQ badging and the sub-brand's signature blue paint finish.
Aside from the special blacked-out color theme, the nightsky packages also feature Brabus-designed exterior components including a unique front spoiler, side skirts and roof-edge spoiler.
The two-tone theme continues inside with a Brabus dashboard and upgraded shift knob, handbrake lever, door sills and sports pedals.
The fortwo and fortwo cabrio nightsky variants will be available in Europe beginning this spring, while the forfour will follow sometime in the third quarter.
