You referring to the the answer as being an Awd Hybrid GT3 with 670bhp in road trim, Yes, That is a stupid thing. I never said anything about hybrids and electrics not being the future.

You mst be a YouTube member lol Internet Tough guy ova heya!

You went from calling it a stupid thing to say to "the smarter inevitable future" Kid you don't know what you're talking about.. You're wasting my time with your dumb and argument dragging speculations Porsche have shown in the past that they adopt the necessary technology to their production lineup as soon as it's necessary take thier pdk transmission for example they've had the technology since the 70's but they haven't deemed it necessary until nissan kinda forced them to work on it for their production modules with the GT-R. Porsche have already produced a racing hybrid 997 gt3 that has 640hp and right now they're testing baseline 911's hybrid prototypes for the production modules.. Stop being so emotional you know that you're wrong kid, deal with it.

We all know hybrids and electrics are the future, Has been all along, But dont expect to see a GT3 with Hybrid/Electric, Awd, 670Bhp for a Looooong time. Nor a GT2 in the same sentence.

Since 991 GT3 and 650s and have very similar lap times I expect (or hope) the same for 675LT and GT3 RS.

Of course McLaren will be must faster in straight line but GT3 RS has huge advantage in corners. GT3 RS is a more hard core car and I'm daring to say that it's more fun too

They've already created an AWD hybrid racer 997 gt3 with 640hp and right now they're working on adopting that hybrid drive train to the base 911's to think that a 991 gt3 hybrid will not eventually come is incredibly daft.. Matter of fact the only reason they haven't done it already is because of the 918. They might decide to brand it as a gt2 rs instead for extra $$ but it wouldn't come turbo charged nor 2wd that's not efficient they won't just increase the gt2 rs's displacement to 4.0l for 650hp or whatever they already know better by now.

GT3 is relfecting their race car models. And TBH, they are making around just 500hp if not a little more in the GT3/GTE series. And they don't have hybrids in there.

For a bonkers supercar Porsche, you'll have to wait for the Porsche GT2 RS

Well good luck waiting for a hybrid Awd GT3 that has 700Bhp.

How is porsche gonna be able to outperform this 675LT and the 488 without adding a new model to their lineup that can come as overpriced as those two ?

Here's what they've said about the Porsche 911 GT3 r hybrid racing car 5 years ago.

So what sort of machine are we really talking about here, and how is it likely to influence Porsche’s future road car development? In simple terms the GT3 RH uses a conventional 473bhp flat six engine mounted at the back, powering its back wheels, while over the front axle it has a further pair of 60kw electric motor that power the front wheels, each developing 80bhp. Which means it has 633bhp in total.

So the answer should be an AWD 4.0L GT3 RS Hybrid making up to 670hp total.
