Got these two toys earlier this year. Complimentary pair.

Congrats, two wonderful additions for the toy studio.

I love them both. Curious your impressions of them.
I've been lusting for an LFA for some time, though the recent market has gotten nuts

I miss my Viper ACR, not very luxurious, but for raw power - it was a beast! Loved the V10 growl.

Do you drive the LFA, or is it a garage queen? A few years back I had the chance to hustle the Lexus LFA test mule around a track (being paced by Scott Pruett so no one overdrove their skills). Amazing car!

Okay, I’ll ask: Indy or anyone else, what’s the advantage of a v-10? It seems like if you want a higher revving engine, go to the v-12, but if you want torque, stick with a V-8 with more displacement and/or supercharging. The balancing of a V-10 is more complicated than an 8 or 12. Is it the sound? Bragging rights? Just because we can?

It gets driven. I've put over a thousand miles on it this year since I got it. It was Larry Ellison's car previously (Oracle dude). Had 4600 miles on it when I bought it in the spring. Sounds very close to the CGT I owned previously. Fit and finish is very nice. Very comfortable interior. Actually like it a bit better than the 599 GTO, although the Pininfarina styling is prettier.

PeteK, that is a fair question. The only v10 I owned was the Viper ACR and it did have a different sound than a v8. Not necessarily better, just different. It also had a ton of torque - over 600 ft lbs. Otherwise, I do not have a good answer...

Well, the V-10 in the Viper I understand. It was a very large displacement truck engine that Chrysler could rapidly adapt for the Viper while minimizing development costs. But I’m curious why a manufacturer like Toyota, who designed a custom engine just for the LFA, or Porsche with the CGT, would end up with a V-10 after doing the engineering trade offs.

And already there's another, 208 miles https://bringatrailer.com/listing/2012-lexus-lfa-6/

Only the 3rd one on Bringatrailer ... compared against 65 GTs (FGT & NGT).

When the Viper came out I remember an article comparing the sound to a UPS truck. lol

Lexus didn't want the nose to stick out like a 70 XKE. Porsche was just being lame.

May have something to do with influence from the F1 V10 era. Not many were ever put into production cars.

Viper 8.0 8.3 8.4
Lamborghini 5.0
CGT 5.7
M5 5.0
Audi 5.2
LFA 4.8

I was also thinking F1 maybe, the V-10 F1 era was circa 1995-2005

If I recall correctly the Cobra concept V-10 was considered for the GT, but time (or lack there of) and cost, gave us the V-8.

I rented a Viper for 2 days in Vegas years ago, and though quick, with all that torque, the motor was done by 5,500 rpm. It did sound like a truck. And the transmission tunnel took up more space than my seat. Did always like the looks of the GTS version.

Here's what Wikipedia says:

The LFA's engineers selected a V10 engine over an equivalent displacement V8 engine for its ability to rev higher,[46] and over a V12 for its lower reciprocating mass,[19][46] allowing for more rapid engine response. Lexus claimed their engine could 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 a digital tachometer which can instantly display engine speed.[57] The engine reportedly weighs less than the manufacturer's own 3.5-litre 2GR-FE V6 engine. Engineers attempted to make the engine sound like that of a Formula One car with high revs, while at the same time maintaining reliability and vibration control. Along with other manufacturers such as Ferrari, Toyota had produced its own F1 engines and chassis designs.[18] The exhaust note has been described by Toyota engineers as the "roar of an angel",[58] and a US television spot later used the engine sound to shatter a champagne glass via resonance frequency.[59]
