No they're not...the V10 is getting replaced with a TTV8 !!! I've seen the 'insider' literature from BMW forums
All BMW atmo V8's and V10's are going to be superseded...
FYI the M3 will get an IL6 turbo, 'insider' literature suggests a tri-turbo IL6 - 1st of its kind...
New 1 series will be 4 and 3 pot turbo powered, turbo 4 for the new 135i variant whatever it ends up being called...
There will also be an M2 in the future...as the M1 nameplate in taken...
