As an owner of a '22 M3 Comp xDrive I will say its a great car, quality is great, the engine is stupendous and its definitely an expensive product but you do get what you pay for.
However Motortrend must have been fishing for clicks because comparing a 4-V Blackwing auto to an M3 comp with xDrive makes no sense. The ideal scenario would be base M3 with manual vs manual 4-V Blackwing or standard M3 Comp vs automatic 4-V Blackwing. I know they said they compared an M4 already so I guess whats the point of an M3 but to me it should be sedan vs sedan not coupe vs sedan, the transmissions should be similar as well as the drivetrain (AWD vs AWD or RWD vs RWD). Anything else and it becomes a bit of a mixed bag. Seeing as how the M3 and 4-V Blackwing are on paper similar in power and both offer manuals, to me its a no brainer so I'm stunned nobody has done a proper comparison between the two.
As it stands its obvious the M3 Comp with xDrive will be a superior product to an automatic 4-V Blackwing, but I guess it better be considering the price difference. Very odd match up, must have been bored around the office.
If Matt Farah is getting a go in a 5-V Blackwing I look forward to his video, he didn't like the standard CT5-V but adored the outgoing CTS-V so I think he will be impressed with the 5-V Blackwing, especially with a manual.
