I test drove a 440i Xdrive convertible this past weekend with the B58 engine. The 440i is a piggy in terms of weight due to the hard top construction and added rigidity but that power plant is great. The B58 might be a modders dream when it’s all said and done. It’s the engine they are putting into the new “Supra” and Z4. Apparently it is constructed in a similar manner to the old 2JZ in the Mk4 Supra. It is a closed deck construction with all forged internals and large/upgrade oil coolers, and a higher compression ratio.
People are speculating that 600-800 hp should be achievable in a reliable manner unlike the N55 limitations.
I don’t want a BMW but it seems interesting none the less.
