One HP is the amount of actual work (and energy) it takes to raise a 550-lb. weight one foot in one second....that is the actual power produced in the cylinders when the air/fuel mixture is ignited and drives the piston down. Torque is the twisting motion, produced from that power, at the engine's output-shaft, when that power is converted to rotation via the connecting rods, crankshaft, and flywheel. It is torque, not HP, that actually propels the car forward when you hit the gas. HP mainly determines how fast the vehicle will ultimately reach at top speed, overcoming air-resistance.

Here you go. If force = acceleration, then the physics at Toyota is obviously broken. Like I said, these numbers are meaningless in the context of Toyota's car. Both.
Now, the first thing we have to address here is the acceleration. Officially, the Lexus IS 200t with the 240 HP engine and 258 lb ft of torque accelerates to 60 in 7 seconds. Ok, that is a nice round number, almost in the realm of hot hatches like the Golf GTI or something. However, the equally powerful BMW 328i (literally equally, it has same amount of torques for goodness sake) can do the same a second faster. A second faster! That is a lot. And if we know that BMW is often rather conservative in their acceleration estimates, we find it hard to believe that the IS 200t is so much slower than the car it wants to beat in the market race. Obviously, Lexus can talk the talk that they aren’t after the buyers of the 3 series BMWs or that they have different philosophy and all of that, but c’mon. One second!

In my opinion it's curb weight and transmissions that Toyota needs to work on. Of course a lighter weight car with a better transmission will accelerate faster than a heavier one with a less favorable transmission, even with the same output.

You never lack energy. But, never mind, I agree this is not the place to argue it. Besides, we're getting off-topic.

We'll see.
We'll see.
Here are a couple new videos out this morning:

All you high and mighty "you don't know the difference between HP and torque!!!" people are probably the same ones that think only 0-60 times matter.

After watching a few vids that showcase the interior it really is something special. Has its own unique style not easy to do, incredible interior actually.
