So this may or may not be very relevant to anyone else's interests here, but I just found out that Lexus is going to produce a hybrid version of their new LC coupe called the LC500h.
Naturally, the first thing I deduced from the headlines popping up after a Google search was that this thing was going to have 354hp.
Now, the last time a six-figure hybrid came out with ~350hp (BMW i8), I pretty quickly got on Facebook and derided that as reminding me of a 20-year-old Corvette. After reading up on it, it ended up being one of my favorite current-production-cars-i-cant-afford and ironically totally undermined any enthusiasm I had for the then-upcoming NSX. I ended up being drawn to its unusual combination of attributes, and despite what the power number suggested, it was still fast enough for 2015.
Obviously the LC500h is not all that similar to an i8 other than being a six-figure hybrid sports coupe with ~350hp of peak system output, but partially because of the i8 I'm looking at it from a much more receptive point of view than I would have a few years ago.
There's another reason I'm receptive to the idea of the LC500h: My GS450h ownership. For the last six months I've had an '09 GS450h as the 'flagship' of my ill-advised 'fleet', and I am LOVING it. It's rated at 340hp peak combined output, but (like an i8, or LC500h!) actually feels faster than it sounds, especially considering it weighs 4100 lbs. Knowing that the LC500h will use an updated and upgraded version of this drivetrain is exciting to me, even if the whole 'gas hybrid' concept is considered obsolete by the time they depreciate into my price range.
One of the things that the auto press seem to be making a mountain out of is the '4 speed auto' aspect of the LC500h. I think it's being misrepresented, for the most part. For those who don't know, the basic idea of Toyota's hybrid architecture for the past two decades (yes, it has been that long!) is to use a planetary gearset with two inputs (ICE and electric motor) instead of one input and one held/locked element as is usually the case with planetary gearsets in transmissions. Using a planetary gearset with one input, one held element, and one output results in a fixed gear ratio. This is where the gear ratios of nearly all 'old-school' automatic transmissions come from. However, using a planetary gearset with two variable speed inputs and one output gives a variable gear ratio that allows a Toyota hybrid transmission to behave as a CVT while being massively more reliable and less complex than the belt-and-pulleys contraption that most people conjure in their mind. The 'ratio spread' that can be achieved with this arrangement is limited by the rpm ranges of the inputs (gas engine and electric motor), so it is only infinitely variable within a certain range.
My 09 GS450h differs from earlier iterations of the system (such as in my 07 Prius) in that it adds a second planetary gearset with a clutch that locks one of the elements (the other two elements are driven by the ICE/small motor combo, and by the 2nd larger electric motor) which effectively makes it a CVT feeding another 2-spd gearbox. The LC500h takes this a step further by including 4 fixed ratios behind its CVT. The net effect of this is to widen the ratio spread of the entire hybrid transmission. This increase in 'gearing under the curve' should result in stronger acceleration. The 1st gen GS450h like mine is claimed to do 0-60 in 5.2 seconds (and the car is definitely very traction limited) @4100 lbs. I suspect the exact same system would be well into the 4s in a lighter chassis with more traction. The fact that Lexus is only claiming a 'sub-5-second' 0-60 from this improved setup makes me suspect it is being throttled to protect the 4.5s gas car with its 100+ additional horsepower. Aside from that, it seems the main point that Lexus is talking up about this new '4-spd CVT' is that it will create a more intuitive (old fashioned?) relationship between ICE rpm and wheel speed so that it's more enjoyable and palatable to buyers.
I'm pretty ok with selling it that way, but I think what's being downplayed in the '4 gears is so old fashioned!' blurbs is that it still functions as a continually variable ratio transmission in all the best ways.
Knowing what my GS450h drives like, it's very exciting to me to think of a super-luxurious Lexus sport coupe taking the same great cruising and WOT experience and cranking it up a notch in the dynamic areas that driving enthusiasts care about, where what happens when you let off the gas, or the first tenth of a second after you floor it, are important to the overall experience. I hope I'll get to drive one of these things in the next few years.
