I still don’t believe that an analog gauge couldn’t keep up with the LFA’s Yamaha V10

I think it’s marketing bullshit.

yeah, especially since it’s an “analog” engine. But it sounds good in marketing.

Same here.

I think it’s definitely a marketing stunt, but I also don’t think they could have used whatever typical motor they utilize in the rest of the Lexus lineup. That thing can spike from idle to 9K in less than half a second or so. That’s pretty quick. But not so quick I don’t think they couldn’t have sourced a motor to to move a physical needle that fast.

You don’t need to have a separate motor just to spin the tach..

I’ll be honest, I don’t know how the average dash is set up. I’m running off of assumptions here.

I think its less “couldn’t keep up” and more “really really hard to see”. With a traditional illuminated needle there might be a persistence of image issue where the needle bouncing around the tach would make its position really hard to accurately judge (it would appear blurry), where a digital gauge with a high refresh would be clearer. however, most auto journalists aren’t scientists (shocked face) and so its easier to just say something cool like “it can’t keep up”

Didgital stuff always seems more laggy to me.

Maybe the mechanism driving the needle would overheat and blow out?

So what? It’s still awesome.

Stack and others make perfectly adequate electronic analog gauges that “keep up” with racing engines that have even less inertia than the LFA’s V10, so I’m sure it’s bunk. More like, “we can’t make our spiffy instruments do all the frippy stuff we want with an analog gauge, so here’s a made up story about it.”

I don’t think that’s it.

If the analog would truly be keeping up with the digital, they’d be moving at the same speed. If the refresh rate is high enough they’d look identical, but the analog needle would have an infinite refresh rate.

Yes you do. Not a V10 of course, but a little electric motor. How do you think it moves?

the illumination wouldn’t though.

Sure it would!

It would need to stay in one spot long enough to be clearly visible to the human eye, though. I guess you’d see but a blur.

In that case the problem is that it’s moving too fast. If you can make it move too fast, I’m sure you’ve the power to slow it down too.

It’s all just ways of saying “we wanted the digital tachometer” anyway, but you’re of course right. They could have just increased either brightness or the needle’s width to achieve better visibility, too.

With everything that’s been said in this thread ... I’m still pretty impressed with a road-legal V engine revving from idle to the rev limiter in 0.7 seconds (if I remember that number correctly).
