I'm not crazy about how it looks but the engineering is amazing.

2011 Lexus LFA: First Drive - Lexus LFA - Jalopnik
Take the carbon fiber, for instance. To make the LFA's, Toyota created one of only two circular looms in the entire world, then used it to simultaneously weave one tube of carbon inside another. They built this system just to make the A-pillars on the car.
The LFA has an unprecedentedly low center of gravity of 17 3/4" — located directly beneath the steering wheel's rim. So far a conventional attribute executed perfectly, but how that CoG got there is way more complicated. First, the engine is located way back in the engine bay and mounts to a 6-speed rear-mounted transaxle through a carbon torque tube. The oil coolers are in the front fenders, while the radiators are at the rear to aid weight distribution, they're fed by the shoulder scoops. That creates a 48% front, 52% rear distribution for the 3263 Lb curb weight. That accounts for the CoG's position front-to-rear, but not vertically. That was achieved by using a world's first counter gear to raise the relative height of the torque tube, allowing the engine to be mounted incredibly low in the car, accounting for the CoG's height.

Still not seeing the Z attributes...when I said maybe I actually had the 370 more in mind than the 350. Definitely didn't realize they were pushing 300K but hey if I had that kind of money to blow on a car I guess I could probably do it two or three times so I would probably pick one up.
Great info there SamS, that's some pretty high-speed **** Lexus has going on for this thing.

Engine
The Lexus LFA is powered by a 72° 4.8-liter V10 engine equipped with dual VVT-i carrying the 1LR-GUE designation with a maximum output of 552 bhp (412 kW) delivered at 8700 rpm. Its maximum torque output of 354 lb-ft arrives at 6800 rpm, 90 percent of which is available from 3700 rpm. The engine, like the Ferrari 458 Italia, redlines at 9000 rpm, but with a fuel cutoff set at 9500 rpm[43] and is constructed using forged aluminum pistons, forged titanium connecting rods, and solid titanium valves. Dry sump lubrication prevents engine oil starvation through high speed corners and reduces the engine's center of gravity. Air is fed directly from beneath the hood through a visible slit passing into a dual stage variable intake manifold and then into 10 individual throttle bodies before finally exiting from a dual stage titanium muffler.

The LFA's engineers attempted to make the engine to sound like that of a Formula One car with rapid revs while at the same time maintaining typical Lexus reliability and vibration control. By selecting a V10 engine over an equivalent displacement V8 engine reciprocating mass is reduced allowing for more rapid engine response. Lexus claims their engine can rev from idle to its redline in 0.6 seconds and an analog tachometer needle could not accurately track the LFA's changes in engine speeds. This necessitated the use of digital tach which can instantly display rpms. The engine reportedly weighs less than the manufacturer's own 3.5-liter 2GR-FE V6 engine.
The powerplant gives the LFA a power-to-weight ratio of 5.9 lb/hp and enables it to reach a top speed of around 202 mph (325 km/h).[44] Like the IS F Yamaha co-developed the engine cylinder heads. The engine complies with Euro V emissions. On the LF-A, the V10 is installed with a front mid-engine placement.[45] According to Chief Engineer Haruhiko Tanahashi a front engine layout was selected instead of a mid engine layout as it is inherently more forgiving dynamically affording less experienced drivers with a wider safety net.

I can't wait to see pictures on the web of one wrapped around a pole, as we all know some idiot with more money than skill will buy one and wreck it! A nice car and will surely put Lexus out there in the exotic car market.
