I thought there was no current-generation IS F because the chassis was not designed to accommodate a V8 engine?

If that was the case, what would be the point of changing this current-generation chassis (which would involve expensive engineering) to allow for a V8, to sell for only 2 years (before the new model)? If there will be a new IS F, it would logically wait for the next-generation, new-platform IS.

I don't believe it. I don't think we will get another refresh. Time will tell, but I am not believing it.

We are going to see the reveal of an all new IS model some time thisyear , unless somehow the current events delay . It was supposed to be revealed at the Ny auto show ........
All new / not a refresh .

Total specualtion but likely . The new IS will use a version of the 3.0 BMW inline 6 from the Supra .....

Hasn't another rumor been no V8s for vehicles under $90k? Not sure how real that one is, but would conflict with V8 IS500, unless the IS is going way upmarket.

Why not just take the TT V6 they already have? Or start going down the performance hybrid route.

Unless they do some magic, the TT V-6 is not a high revving sports sedan engine. Its a low torque big sedan engine. Not sure how big it is either. But if they can adapt it to the IS F, I am all for it. The thing is the C63 AMG already has 500hp or so. New M3 will surely get a bump etc...

E-axle could address that, no? Make the F-Sport the hybrid-performance version. Didn't they have an ES mule with some prototype system a little while ago?

If that is even credible information it needs to be rescheduled to sooner than that and likely NAIAS. It is up to them of course, but scheduling is not looking pretty.

The original info I posted about a reveal at NYAS was credible . I’m sure about it.
Now there is just no way to know what they will do , it’s not the priority at the moment.

I am pretty sure they would have done it online instead if production model reveal was in question. Maybe it was some concept preview?

Using the E-Axle on the FWD-based ES, turning what is essentially a FWD cruiser into a more sporty AWD vehicle (by using the powerful E-Axle on the rear axle), makes sense, but it makes no sense (to me) on the RWD-based IS. Why put so much front-end torque on an already sporty RWD vehicle?

And I am not sure that there would be the room under the hood (and under the engine) of the IS for a large E-Axle.

If it is possible to make a quicker, faster, sportier IS by hybridizing the TTV6 from the LS 500, leaving it RWD (or mechanical AWD without the E-Axle) it would make sense.

Why does a V6TT need to be high revving to be a F engine? It's not like the 650hp Ecoboost on the Ford GT revs particularly high. The V35A-FTS is already capable of 6,500 rpm and most high performance turbocharged engines have similar redline.

In fact I feel it's a waste if they don't scale the V35A-FTS to beyond 500hp, as the engine is heavily over-engineered already. All they need is transplanting the G16E-GTS (from Yaris GR4) turbocharging setup and they could breeze past 550hp.

E-axle would be very tricky to integrate onto a longitudinal RWD setup since it would just be a packaging nightmare. The whole point of E-axle/E-four is so that there's no mechanical link between the front and rear, with only electric power flowing to tweak the torque distribution. But in a longitudinal RWD setup there's always the propeller shaft.

And I am not sure that there would be the room under the hood (and under the engine) of the IS for a large E-Axle.
Even if they magically found space in the engine bay the car would be so front heavy it would drive worse than a FWD vehicle. The only time a front E-axle makes sense is if the car is MR layout like Acura NSX or LMP1 hybrids.

Absolutely but from my understanding that is still some years away. I also assume it will work first with an electric vehicle.

The current F cars redline safely at 7200 RPM. They are big 5.0 V-8s with peaky power and lower torque. Signature to the lineup for awhile now. I see what you are saying but 6500 RPM is pretty meh to me even with 700hp. I would prefer the engine to scream a bit.

But who knows. It seems internally they are hard at work with new engines, tech and electric stuff...

Because naturally aspirated engines have everything to gain from higher revs, higher revs means more air sucked in and thus more power. BTW I'm very upset the 2UR-GSE is capped at 7200rpm even though it's totally capable of 8k+.

There are few turbocharged engines out there that would rev past 7k. And it's not like turbocharged engines even benefit from high rpm, since their power is limited by boost pressure and compressor flow rate, not rpm. They would just be 'screaming' for nothing.

I've said it ad nauseam several times, but I'm convinced that the TT V6 in 5LS is held to only 416 hp because if it were any more powerful in that 4700-5000 lb car it would incur a U.S. EPA gas-guzzler penalty, a huge no-no for Toyota/Lexus (LFA and trucks excepted). Put that TT V6 in a lighter 4IS F and it would surely be tuned for more power.

With electric motors, sky is the limit with configurations. Acura Sport Hybrid SH-AWD already allows this.

For the NSX (engine mounted in the rear), two electric motors in front and one motor in the rear.

For the RLX/MDX (engine in front), two electric motors in the rear and one motor in the front.

Honda's pretty good though. They were able to convert the NSX to a front engine to qualify:

Shouldn't the e-axle or higher end e-awd also afford the flexibility? In a straight line, a FWD or RWD will feel the same. It's when the car isn't traveling straight that torque vectoring helps anyway.

Toyota/Lexus, when are your bringing out the IS PHV?

For those outside Canada, the reason BMW priced the base model at below $45k is to the car eligible for the $2,500 PHV/EV rebates across all 3 Series PHVs in Canada below $55k (I believe). Maybe we will see a $44k CAD 4IS PHV in Canada in two to three years' time.


BMW late March revealed the Canadian pricing for its new 330e and 330e xDrive plug-in hybrid sedans, giving the RWD variant an MSRP that just barely qualifies it for the federal EV rebate.

The 330e is BMW’s plug-in hybrid variant of the 3 Series, and features a 2.0-litre turbocharged four-cylinder that produces 181 horsepower and 258 lb-ft of torque.

Combined with a 113-horsepower electric motor, total output works out to about 288 horsepower and 310 lb-ft of torque.

Power is sent to the rear wheels in the base model; or to all four in the xDrive-spec version. The RWD model has an MSRP of $44,950, while the xDrive model carries a premium of $54,000 MSRP.

So how and where is this 2021 MY IS coming from? I said 2022 for sometime, yet we heard 2021 for some reason without any mules or prototypes being seen.

What gives is my wonder? I mean really? USA CEO has said only LC this year and I knew this originally to be correct, unless he is lying. There has been no proof of anything coming this year.
