BMW Fxx/Gxx B58 OBD Flashing is now supported by mFlasher by Missionperformance

Info on the next generation of BMW engines, including the B37 will not get any major updates in RWD models anytime soon. The transverse (FWD) version has a TU planned. No new versions are planned.

B38 will get TU for all existing versions (starting with the recently updated F48 sDrive18i), with the exception of the 1.2L one and the one that goes into i8. No new versions are planned.
B47 is simple: TU for all versions with the exception of longitudinal 16d (will be dropped?)
B48 is starting to get its first TU (now available in Europe in F48 sDrive20i). The TU version will soon find its way into more UKL models, and then we’ll see it in the CLAR cars, either with 07/18 “model upgrade measures” in G30, or at G20 intro. The only new version of this engine currently planned is the one that will go into UKL M35i, B48A20T1. The longitudinal versions will remain limited to 20i (B48B20M1) and 30i (B48B20O1).
B57 – TU for 30d and 40d, but not 50d.
B58 will get a TU (probably mid-2019), and with the TU will come a new version, B58B30O1. Note that up until now, all models, even the highest output X3 M40i, have been using the M0 version of this engine. O1 will probably take us even closer to 400hp, and I won’t be surprised to see new model names (M45i? though don’t quote me on this).
N63 is currently in its third iteration (TU2), and there will be the fourth one (TU3) that will add two new versions, one below (M3) and one above (T3) of the current O2 (to be succeeded by O3). This actually looks somewhat illogical to me, since the future top version of B58 and the future bottom version of N63 should end up really close to each other in output. I suspect one of them may not actually happen.
N74 used in the brand new Phantom is actually one iteration ahead of the one in M760i (TU2 vs TU1) in addition to being bigger (6.8L vs 6.6L). M760i will catch up with its own TU2 soon, but there will also be something new, probably RR specific (Cullinan Black Badge?): N74B68M2.
S55 will not get a TU, but will be replaced by S58 (full name S58B30T0), as we already know.
S63 just got its newest upgrade in F90. It’s going to stick around for a while.

The new BMW 6 Series Gran Turismo is fascinatingly elegant, highly versatile and outstandingly dynamic to drive. In order to demonstrate the sporty character of the model, the model-specific BMW M Performance Parts will already be available at market launch in November 2017. The customised and motor racing inspired retrofit parts for drive, suspension, exterior and cockpit enhance dynamic driving even further and give the new BMW 6 Series Gran Turismo an individual and powerfully expressive appearance.

The well-established racing expertise of BMW M GmbH, which was made use of in developing the parts, is reflected in the authentic style of the BMW M Performance Parts range. All components are fully subject to the high BMW Group standards in terms of material selection, design and quality of workmanship. Retrofitting these items has no impact whatsoever on the warranty terms as applicable to the vehicle in question.

The BMW M Performance exhaust silencer system gives the new BMW 6 Series Gran Turismo a truly impressive acoustic and visual dimension. It gives the rear a striking look and ensures a sporty sound which is, however, also suitable for long-distance travel. The silencer is made of stainless steel and was especially developed for the petrol engine models BMW 630i Gran Turismo (combined fuel consumption: 6.6 – 6.2 l/100 km; combined CO2 emissions: 152 – 142 g/km), BMW 640i Gran Turismo (combined fuel consumption: 7.4 – 7.0 l/100 km; combined CO2 emissions: 169 – 159 g/km), BMW 640i xDrive Gran Turismo (combined fuel consumption: 8.2 – 7.7 l/100 km; combined CO2 emissions: 187 – 177 g/km). Depending on engine type and equipment, it comes with either round or trapezoid tailpipe trims in chrome or carbon fibre. The round tailpipes feature an engraved M logo and the trapezoid tailpipes the M Performance inscription.

Driving dynamics and visual appeal of the new BMW 6 Series Gran Turismo both profit from the 21 inch BMW M Performance light alloy wheels. They are manufactured using weight-saving forging methods and feature a two-level double-spoke design in bi-colour composition. The high-gloss paintwork is combined with burnished surfaces for the outer spoke level and the wheel rim. The exclusively designed wheels have mixed tyres in the sizes 245/35 R21 on the front axle and 275/30 R21 on the rear axle, complete with emergency running properties. The sport braking system, which is also available for the new BMW 6 Series Gran Turismo, optimises both the dynamic driving experience as well as the car’s visual impact. Even when driven in extremely dynamic fashion, the new BMW 6 Series Gran Turismo achieves constant braking performance by means of inner vented, perforated lightweight construction brake discs with 4-piston fixed caliper brakes made of aluminium on the front axle and single-piston floating caliper brakes on the rear axle. Red brake calipers serve as a visual indication of the fact that the design of the BMW M Performance sport brake system is derived from motor racing.

The high-gloss black BMW M Performance kidney grille gives the front of the new BMW 6 Series Gran Turismo a specifically dynamic look. In combination with the black trim bars of the air flap control, the BMW kidney grille receives a perfectly colour harmonised appearance.

The BMW M Performance exterior mirror caps in carbon fibre are yet another visual highlight. The components made of carbon fibre reinforced plastic (CFRP) are elaborately crafted by hand especially for the new BMW 6 Series Gran Turismo. Multi-layer paintwork and high-gloss finishing give the car’s surfaces their striking intensity. The BMW M Performance Frozen Black foil superbly accentuates the sporty-elegant lines and the harmonious proportions of the new BMW 6 Series Gran Turismo. The matt black and grey trim stripes match the car’s geometry perfectly.

The BMW M Performance sports steering wheel gives the new BMW 6 Series Gran Turismo a special motor racing touch inside the cockpit. Its alcantara-covered grip areas, large thumb rests and the slightly flattened lower section make it a pleasure to hold, provide optimum grip and ensure direct steering response. Soft nappa leather both in the upper and lower section as well as on the steering wheel trim, a silver-grey cross-stitch seam and the red central marking at the 12 o’clock position round off the highly dynamic design of the BMW M Performance sports steering wheel. It also features shift paddles for manually selecting gears in conjunction with the 8-speed Steptronic sports transmission. BMW M Performance foot mats are also available in the cockpit product range.

The model-specific retrofit options from the BMW M Performance range will be available right from the launch of the new BMW 6 Series Gran Turismo. All products form part of the Original BMW Accessories program, sold and installed through the BMW dealer network, BMW sales subsidiaries and BMW Service Partners.
