Motortrend: LFA vs. GTR
#51
The GTR is obtainable for enthusiasts to purchase. As for the LFA, one has to jump through hoops & squeeze the rosary tight to be one of the selected. I am suprised the testers were able to get an LFA to the track on time for the comparo I kid, I kid... The car was anted up by Lexus..

"It is also a preproduction prototype -- a crusher in industry parlance. It has no VIN or license plate, and sits on non-DOT-approved tires, so we can't drive it on the street. When we're done with it, it gets shipped back to Japan where it will likely be reduced to a fine, expensive powder."

damn, can't get enough of that exhaust note
don't bother arguing
Why waste money on a GT-R when you can a bucket civic, load it up with tons of NOS and it'll be faster than both of these cars
Plus, you got plenty of money left over to add on a hood scoop, fender vents, a couple of stickers, and a huge shopping cart wing for that downforce

A couple things to note on this dyno chart:
- A Superflow dyno was used instead of the typco Dynojets. This is an inertia loaded dyno meaning it will typically read lower, but is much more accurate in terms of WHP measurements.
- GTR is definitely underated at 480bhp. 21% driveline loss for an AWD is incredible! LFA w/ 22% driveline loss is pretty typical of RWD.
- GTR has tons of power/torque down low, as it was really tuned for the street. The LFA's V10 was made for hi hp and top speed. Having a very linear lower torque makes it so much easier to get on the throttle mid corner (think F1) and the 9500rpm or so fuel cut off is insane!
And this picture is just phenomenal (kudos to the MT photographers!)

"We get a lot of big power hot rods in here -- like this Nova last week that made over 1400 horsepower to the wheels. I'm used to older cars that vibrate. You know you're going too fast because things start to rattle. This is thing is so smooth and fast," says Dave. "You can get into a lot of trouble with this."

Correct me if I'm wrong here, but the article clearly stated this LF-A is a preproduction prototype and from what I have heard the prototypes are aluminum and NOT carbon fiber. This would explain the extra weight. I can only imagine had they tested the production version there would be even more gap in performance between the two.
"It is also a preproduction prototype -- a crusher in industry parlance. It has no VIN or license plate, and sits on non-DOT-approved tires, so we can't drive it on the street. When we're done with it, it gets shipped back to Japan where it will likely be reduced to a fine, expensive powder."

Motortrend stated this was a prototype, a crusher. Why would they send a production car with a carbon fiber chassis to the crusher? Why not let one of the LFA's head staff have it? It's because this has to be an aluminum chassis car that's just had the production body. That's the most logical guess as to why this car and the one reviewed by Car and Driver weigh over 3500 lbs. Didn't lexus say the weight savings for carbon fiber vs aluminum was 300 lbs.? There's you're weight difference!

I wonder if Lexus wouldn't want me to take one of the pre-production prototypes off their hands instead of going through the trouble and emotional stress of sending it to the crusher?
No?
Drivetrain, brakes, suspension and seats then?
Pretty please?
With a cherry on top?

a Carbon Fiber BODY is different than a Carbon Fiber CHASSIS. The Chassis on the prototypes were Aluminum up until last year. It's a possibility that these 'crusher' cars are aluminum chassis cars. There was someone on these boards that spoke with the Lexus people at one of the events and they told him that the LFA's with the Aluminum bodies are demo cars. Maybe this prototype was one of those demo cars.

I see carbon fiber on the body, where in the chassis can there be visible carbon fiber? the body is on top of the chassis. The body is made of CF, I don't know what you're trying to tell me to look at. I don't see a chassis with carbon fiber.
All i see is the rear and according to lexus the front and rear crash structures are made of aluminum. The tub is made of Carbon Fiber.
