In the autumn of 2023, Claas introduced the Evion as its smallest model series. It shared a large part of its technology with the Trion, but the Evions were manufactured in China. The threshing mechanism had 5 concave bars and a threshing drum width of 142 cm. There was always one threshing drum. The concave bars were the same 440 cm ones as in the Trion 500 series. The engine was a 6.7-liter Cummins Stage V. The power rating of the largest Evion 450 was 258 hp, and, for example, the grain tank capacity (8,000 liters) was the same as in the smallest Trion. The transmission was mechanically controlled and had three gears. The grain tank unloading rate was 90 l/s.

All Claas options were available for a cutterbar up to 6.8 meters. The folding header was available in 4.5 or 5.4 meters. The base model Classic was designed for grain threshing. The parallel model Maxi (not the 410) was also suitable for maize, among other crops. It featured two speed ranges for the threshing drum, interchangeable concave segments, a differential lock, and an adjustable rear axle. Concave adjustment was hydraulically controlled as standard, and the sieve system was electrically operated. Basic information about the crops to be harvested could be stored in the Cemis 700 terminal (7 inches). Also standard was the Auto Crop Flow monitoring system to prevent blockages, which first warned the operator and then disengaged the cutterbar and feed drive. The Trend equipment package included a standard 52-blade chopper, and the Business package included a 72-blade Special Cut. Additionally, the Business package featured, among other things, a refrigerated compartment, electrically adjustable mirrors, a work lights Plus package, Auto Contour automatic header flotation, and 3D cleaning that distributes material across the upper sieve in the transverse direction. The cabin noise level was reported to be 76…79 dB.
