0 to 60 in 4.9 is not the same as 0-60 in 4.3. So Perfomance is not the same.
Also the electric engine seems to stay engaged to 87mph or so and then it's off.. So no way a 3.5 V-6 will keep up as speeds rise with a 5.0 V-8.
And mind you I owned a GS 450h and RX 400h.
To me it should be 400 or 450h but I would still buy it as a 500h
oh, but you misread it
It is Geneva PR, so it is 0-62, and they say "significantly under 5s"... So lets assume 0-62 is 4.8s... GS450h European 0-62 mph is 5.9s. GS450h US 0-60mph is 5.6, so assuming same 0.3s difference, we get 0-60 in 4.5s.
As to the electric motors, thats not how it works. Maybe in some other cars, but with Toyota and Lexus, they work at any speed. What they talk about at up to 87mph is electric-only power. That means you can cruise in EV mode at 87mph (no gas spent). New battery and new motors also mean that new LC500h has 50% more instant electric power available compared to current GS450h... So that kick when you pressed pedal in GS450h will be 50% stronger in electric hp (60hp vs 40hp) as well as stronger due to better gearing (under 30, over 70)
At 100 mph you still get electric motors to assist you, they just wont power the car on its own... and engine will still shut off if you are braking at that speed. Significance of 87mph EV only is that at that speed (which is basically what 95% of Europe and 100% of NA drives at max), it will go between EV and engine to get best mpg (pulse & glide), basically making it possible to double the mpg on hway. Current GS450h can do this up to 62mph which is too low to be useful at any kind of highway. G3 Prius can do it up to 42mph. G4 Prius can do it at 70mph. Since more energy is recovered, more is available for pulse and glide as well.
Beauty of gear reduction of LC500h is that it brings enormous benefits to mpg and performance both.
So compared to your GS450h (i know you had great looking one), difference is that reduction gears provide more engine speed at startup (more torque available) and at high end where previous hybrids had very low limits due to limited gearing. Now Lexus Europe said that maximum speed of LC500h will be much higher than of their previous powertrains (which are currently limited between 160 and 200kmh, low for Germany). So where before, GS450h felt great between 30 and 70 mph, this thing is accelerate great at all speeds and have a normal top speed.
And then we get to overdrive 4th gear, that makes it possible to cruise at high speeds at very low rpm as well, which again was a problem with hybrids that did well up to 60 mph but above that they would spend way too much fuel. So higher end gear and plus EV-only at 87mph means highway fuel usage will be much lower than before.
Prius G4 for instance has been tested to better Jetta TDI at steady 70 mph due to similar improvements (longer gearing, EV was not activated), where previous G3 could not touch it (5 MPG difference). LC500h will do really great up until 87mph and still good after that.
So ability to feel the gear changes is just the 3rd one on the list for me... with performance and mpg being vast improvements from before.
