I have a few opinion toward this "LFA successor" , as well as a personal point of view , to reply to the current comments in this post ... I hope I won't offense you guys when I'm voice my opinion (since you know , this opinion can be real personal centered) .
Firstly , I see this as serious upmarket hypercar , the kind of hyper hybrid like Porsche 918 Spyder , McLaren P1 , and Ferrari LaFerrari ... this is no ordinary supercar like your Lexus LFA or Lamborghini Aventador LP700-4 ; on (rumour) paper , it utilized TMG's 3.7-litre V8 , as well as combined with hybrid system to makes somewhere between 800 to 1000 horsepower , that is nothing but a beast like Porsche 918 ! If Lexus-BMW did it correctly (given not being heavier than 918 , or messed up stuff) , they couldn't made one hell of beast right there !
For some reason , the quote of "The power source for BMW’s supercar will be a bespoke M-developed straight-six twin turbo with plug-in hybrid technology courtesy of Toyota." sounds like the recipe of the Toyota-BMW coupe that had been talked about ever since Toyota-BMW had co-joint venture .

What about putting it this way ... just take it as hypercar , not as LFA successor , but something one up LFA .
Lexus didn't have such an epic powerplant before LFA (or IS-F) , but they managed it ... so why not a crazy hypercar ?

The V8 doesn't sounds too bad IMO , but if combination with V10 , is also a good idea , love to see the engine come back one more time .

From what I understand , Porsche made the 918 engine based on a race car engine ... same thing on Porsche's Carrera GT ; I have faith that Lexus-Toyota able to made the TS040 engine being production ready ... but it might need quite a lot of redesigns .
