Holy crap. 208hp per liter on a PRODUCTION ENGINE. For torque it makes 369ftlbs.
I know tuners have been making even bigger numbers for years but this will be a factory motor with a warranty. Big.

Being able to mass produce and warranty something like that is damn impressive.

I'd be changing the oil & plugs like crazy in that.
Typical US consumers don't maintain their vehicles very well. On a high-tuned poodle engine that's a recipe for kabooms. |

It made big news when they released specs a few months ago. Good to see them pushing the envelope on automotive IC engines.

Modern oil does well in high temp environments for many miles. Modern ECU's will pull power and even shut off cylinders well before a plug gets bad enough to cause a kaboom. |

Does it make choo choo noises?
How much more can be squeezed out of it with a tune and E85? Will it fit in an early 70s 300d? I love V8s as much as anybody but I can appreciate a high strung boosted 4 banger too. |

Very impressive and would be incredible in a sub 3k pound RWD.
I wonder how much, if any, of this is a result from their current dominance in Formula 1. |

There was a big jump in power (and complications) with direct injection.
They have forced induction pretty well dialed also. Put these 2 together and you get some damn impressive numbers. Problem is the motors are built to the very minimum to handle that power. Used to be you could easily grab another 100hp with just a tune (FI), and the motor was good for 2x its stock output if you started throwing bolt ons at it. Now it seems they are so close to the ragged edge out of the factory, you risk shit like wiping the rings off the pistons if you turn them up. Its like they gave up on keeping people out of the ecu, so they figured theyd give them a reason not to poke at it in the 1st place

HP per liter is a useless metric. Power/weight is what's important, along with efficiency and reliability.

it's just cylinder pressure...thats right around the bmep of current production diesel engines and they run forever in applications that use every drop of torque at high duty cycles.
once you add turbos it's just a matter of building things heavy enough to put up with the amount of power you want. built it to put up with cylinder pressure and the rpm will make the HP |

From a production car standpoint achieving 208hp per liter is an accomplishment even if the engine isn't NA. |

To put things in perspective for our knuckle dragger members this would be like Chevy putting a turbocharged 350 into a production car that makes 1185hp.
Now tell me this isn't a major achievement.
