That is quite a commendable achievement. To compare, the Carrera GT's 5.7L V10 also does not have direct injection, and it achieves 605 HP, or 106 HP/L. The LFA V10 exceeds the Carrera GT's HP/L easily.
The LFA also easily exceeds the HP/L of the Audi/Lambo 5.2L V10, and the BMW 5.0L V10.
Direct Injection gives anywhere from a 10-15% increase in power, as well as fuel economy. Toyota's D4-S direct injection system gives roughly a 14% power increase.
If we do some rough calculations for the LFA engine, with direct injection it would be making roughly 629 HP, or 131 HP/L.
Just some food for thought.

Definitely. To those who compare this to the Ferrari F458 figures, the big difference is the Ferrari engine has direct injection. The F458 4.5L V8 makes 570 HP, or 127 HP/L. The 4.8L LFA V10 makes 552 HP, or 115 HP/L. However, the LFA engine achieves this without direct injection, unlike the Ferrari.

So here are a few more interesting tidbits:
- the car does have launch control
- apparently, the claimed 3.6 seconds 0-60 mph time from Lexus was achieved without using the car's launch control (it looks like Toyota is being coy about the car's true performance potential)
- at 202 mph, the LFA generates over 552 pounds of downforce
- the engine doesn't have direct injection; Toyota could have added it, but felt it wasn't needed, partly because F1 engines don't use direct injection

3.5-3.6 secs w/o the launch control. I wonder what it is with the launch control. 3.2-3.3 secs ?

Another tidbit somewhat mentioned earlier in the thread:
- the LFA does in fact have an amazing turning circle; it is 19.7 feet. To compare, an IS F has a turning circle of 33.5 feet
.
With launch control, I fully expect the car to be able to achieve a 0-60 mph time of at least 3.3-3.4 seconds, maybe lower.
Toyota's D4-S system gives roughly an 11% increase in torque. If the LFA V10 had direct injection, it would be making roughly 629 HP and 393 lb-ft torque.

Turning circle comparison
Also here are some other turning circles from a variety of cars, just for comparison purposes:
Lexus LFA: 19.7 feet
Porsche 911 GT2: 35.7 feet
911 GT3 RS: 35.8 feet
Ferrari Enzo: 40.4 feet
Carrera GT: 42.3 feet
Lamborghini LP640: 41.2 feet
Nissan GT-R: 37.4 feet
Ferrari F50: 41 feet
McLaren F1: 42.7 feet
It really is quite stunning that the LFA has such a tiny turning circle. Typically you only see such turning circles on race cars.

yeah i think i brought up about the turning circle first. it's insanely small compare to any of the other competitors. so small that indeed i wonder if the number is correct. but then again it's on all the lfa official spec so i am quoting that. the dark side of me is still pretty skeptical, it's a big gap between the lfa and other cars

I'm sure you guys aren't tired of seeing pics so here are some more from the Tokyo Motor Show, courtesy of supercars.net 
Looks wicked from this angle right here (below)
