Lexus RX Prototype Spied

Quote:
...

The Lexus designers have clearly focused on evolution rather than revolution for the next generation model, the overall body profile remains the same, but we will see a more modernised design using the LF-Xh Concept as inspiration.

At launch the engine line-up which includes the 3.5-liter V6 will stay largely unchanged but further down the line we should see the introduction of a 400 horsepower powerplant. Production for the new model will commence in late December before going on sales early in 2009 as a 2010 model. We should see its worldwide debut at the Paris Motor Show in September.

Does it look like a Venza?

A 400hp powerplant in the future? What engine would that be? Would Toyota try to shoehorn a V8 sideways into the engine bay of the RX? Could that mean that the Highlander would follow, and a high-performance Camry? The RX has always been based on the Camry platform, after all.

I doubt they'd put a V8 in there. A 400hp makes more sense as a V8 option. On the flipside, a 400hp makes no sense and 300hp seems more plausible. Also the rear gets more slanted every generation. It's already looking like the IS SportCross. Hopefully it doesn't become the X6 in 5 years.

I don't think the V8's would fit in there unless they develop a new narrow angle V8. Maybe we are getting a supercharged engine, but that still doesn't explain 400hp. I don't see Toyota getting back into turbocharging bigger engines anytime soon.

My guess.. would be 400 hp.... 306hp from the 2GR and 94hp from Electric Motors! =)

My guess is the V8 will be the for the "F" performance version. They have 5.0ltr engine in the IS that is a little over 400hp so maybe its the same engine??? Tuned differently for the size of the car but you get the point.

At this point I don't see them putting a V8 in the Highlander or Camry. With gas prices the way they are I don't think Toyota will go Chrysler on us. Not to say a V8 won't be nice but most consumers aren't concerned about that. Performance for Toyota? Humm, since we're shafted on the new Toyobru I don't think that's going to happen either. Yeah I'm a pisser Toyota is having a hard time selling cars like the Highlander as it is. A V8 won't help. I'm very curious what they'll do for the next gen 4Runner. Maybe incorporate their Valvematic in the V6 versions to increase mpg. Who knows!

No disrespect, just pointing it out Sulu

ECHOKnight2000, I do not consider your comments disrespectful. I always respect the comments of others who are adding to civil discussion. What bothers me are those posters who have no respect for civil discussion.

I was merely thinking out loud here. If the new RX is still based upon the Camry platform, and if a V8 can be shoehorned into the RX, perhaps it can be done in the Highlander or the Avalon or the Camry. (Some of the speculation I have seen about the next-gen RX seemed to me that it would no longer be based upon the FWD/AWD Camry platform, but a larger, RWD platform.)

But just because it can be done does not mean that it will be done, for any number of reasons, a number of which you pointed out. Who knows, maybe it will be a turbo-charged or supercharged engine (like in the TRD version of the Australian Toyota Aurion)? Or maybe it will be a performance-oriented hybrid system? (Honda is considering producing a performance-oriented hybrid as the next CR-X, and there are rumours that Nissan is considering doing the same thing by producing a performance-oriented hybrid model.)

(Note: I had missed TRD-MX83's comment when I added my comments regarding performance-oriented hybrid models. Obviously, I agree that the 400hp could be the result of the 2GR + HSD.)

the Venza is based on the Avalon platform, and if this is a "near clone" of that, then I do not know what could go in...

Thanks Sulu!

Well we don't encourage thinking let alone out loud on this forum but since you're my buddy I'll let it go this time

Just kid.

I see what you were saying. That a V8 in car A can probably be put in car B or C. If not from factory maybe someone doing an engine drop.

Me too wonders about how much improvement the 4runner fuel economy will get.

I don't know but the 4Runner has never been the fuel economy champ. It was running on that... 3.4 litre engine for ages. I'm curious of the new technology can be tuned for extra tq cause right now, the FJ, 4Runner and Tacoma need something more fuel efficient thank the current 4.0 litre.

That 4.0-litre engine does belong to the GR family (1GR), so why not put on the cylinder head, fancy valvetrain and Dual VVT-i from the 2GR? Unless there is no more room under the hood for it. I read in some thread here that the cylinder head on the 2GR takes up a lot of room, making the 2GR a very tall engine.

Well yeah I figured they have a "truck" engine lineup. Maybe it was tuned for torque? In which case, I'd think turbo might help better or simply a turbodiesel.

ahhh I see. Which fits nicely with the passenger cars cause their hoods need to be raised for pedestrian safety anyway.

Yeah, I figured that the 1GR is the truck engine of the GR family. Which makes me wonder if the new AR (?) family (the new 2.7-litre Venza and 2.5-litre RAV4 engines) would include a truck engine designed for lower horsepower and tremendous low-rpm torque to replace the 4-cylinder engine currently used in the Tacoma. That way, Toyota reduces the number of different engine families in its lineup. Toyota has done that with the GR family (1GR) and the UR 8-cylinder engine family (3UR 5.7-litre engine).

My understanding of the high hoodline is so there is more crush space -- empty space between the top of the engine and the hood -- so that the hood has further space to crush before hitting the engine, making it safer for pedestrians who have been hit. So, there is still no room for a taller engine.

hmm I see. Well anything to get off the current 4.0 litre. It's thirsty as hell.

I suppose but a taller hood also means less bending over, reducing the speed of the the impact (not sure if it reduces the force on the head)
