NO Official word BUT as of now and currently available information, Civic XI is no where before April. Again this info is same as we all share through our sources.
Keep in mind, even if Atlas has vehicle ready to reveal, a delay helps them as they are getting prebooking and that deposits earn them profits. Once the vehcile is publically revealed with price, then they go under pressure to deliver a vehcile to consumers. I think as of now dealers are taking prebooking but no offical word from Atlas.
After couple of months Atlas will also officially start prebooking , means officially announce prebooking but still without the reveal . Then after another month or so, they will release the vehcile with price. This is exactly they did with City and few years ago with BRV or even Civic X and I suspect same will happen with Civic XI.
