Through a post on their X page, AC Evo developers Kunos announced that, on May 7th, they will release four new cars as part of Early Access Release #2. Those cars are:

Maserati GT2 – A triumphant return to GT racing. Refined through years of competition. A track beast with Italian soul.

Lotus Exige V6 Cup – Lightweight, razor-sharp, and track-tuned for pure performance.

Alfa Romeo Giulia Sprint GTA – A high-performance twist on a timeless icon. No electronic aids, pure driving.

Alfa Romeo 75 Turbo Evoluzione – Born from motorsport. Aggressive aerodynamics, raw turbo power, and racing spirit.

Those four cars are part of a 7-car release for the 2nd state of the sim's Early Access program. Other content that's included as part of that are two tracks (Donington and Circuit of the Americas), open mode/career mode, single player/custom race weekend, new special events, replay tools and gallery, VR support (step 2) and triple screen support (step 2).
