My M2 predictions based on what we've learned from the M3/M4, SCOTT26's input, and automotive trends:
Engine: N20 derived S20 I4 engine. Displaces 2.0L with a turbocharger, air-to-water intercooler like the S55. Power output between 300 and 330 HP; yes, the same or less than the N55 in the M235i. The usual forged crank upgrade and other light-weight components will be highlighted.
Weight: Weight reduction in the area of 8-10% when compared to the M235i. Target (unladen) weight around 1400 kg [1]. Light weight will be a major focal point of the car, slotting in right behind road holding and agility ("dynamics").
1: Based on leaked "unladen" weight of 3373.1lbs from
Bimmerpost official M235i specs thread. My prediction is that it will be 8-10% lighter, which means the target weight may be adjusted up or down based on the published US curb weight of M235i (currently not listed on the BMW website).
Performance: The M2 will not focus on blazing fast acceleration or quarter mile time, but will excel in road holding and handling. 0-100km/h acceleration will drop in right between the fastest 2-series (M235i @ 4.8s) and the slowest M4 (M4 6MT @ 4.3s), coming in at 4.5s to 4.6s.
Chassis: In order to achieve the 8-10% weight loss, extensive use of carbon fiber will be seen, especially at the extremities (fenders, trunk lid, etc). The goal will be to keep the car's mass as close to the center as possible for a low polar moment of inertia. This quality will give the car an agile feel that will surprise automotive journalists. Look for creative positioning of components like the battery (maybe even under the back seat).
Pricing: Price will be well north of the M235i coupe in order to protect up-line models, filling the pricing gap between the 435i M-Sport and the M4. Look for a base price at around $52,000; a $5,000 increase over the base 1M Coupe price.
Memorialized here for future embarrassment when I'm completely wrong. I'll post a photo of my face covered in egg if they release a $45k, naturally aspirated, 8k redline, 333 HP, S25 powered M2 that weighs 1250 kg and does 0-100km/h in 4.0s
