Lambo to the limit(er): PH Blog

Does the Huracan's virtual rev counter prevent you from getting your full 610hp?



As YouTube comments go an accusation of not having big enough guns to drive a Lamborghini Huracan has to be one of the more amusing. "Bro u even lift? #chickenarms" asked an apparently outraged 'Crispy Surf' in one of the few comments not to pour scorn on the repeated headbutting of the rev limiter in our onboard video lap of Ascari.

'Chickenarms' Trent about to hit the limiter
'Chickenarms' Trent about to hit the limiter
Quite reasonably the general gist was 'just how rubbish a driver are you to not be able to upshift an automated gearbox before the limiter?' Only expressed in rather more forthright terms, as is the typical YouTube commentator's forte.

Now if I was particularly worried about what YouTube made of my driving I'd have not put the lap up but the rev limiter issue on the Huracan is an interesting one. On my first few laps I left the Anima switch that controls everything from throttle to dampers and gearbox to stability control in Strada and then Sport modes. In the manual setting I was surprised to find it upshifting automatically some fractions of a second before I was even reaching for the right-hand paddle. Which seemed unnecessarily cautious. So into Corsa mode and the promise of the full range of the rev counter.

Now, your full complement of 610hp - it's written on the side of the car - doesn't actually canter in until the engine's turning at a rowdy 8,250rpm. According to the rev counter the red line is at 8,500rpm. But it's proper peaky normally aspirated motor so no complaints there. Thing is, when you're chasing a man in an Aventador you need all the horsepower you can get but on several occasions I hit the rev limiter just before I was about to upshift. Wary of this I got more cautious about when I pulled the + paddle, to the point where when the 'needle' on the simulated analogue rev counter in the Huracan's fancy new TFT screen reached '8' I'd pull the paddle. Even that wasn't always quick enough to make the shift before the limiter.

610hp - but can you actually access it?
610hp - but can you actually access it?
Either there's lag in the response to the paddle, the dual-clutch transmission wasn't shifting fast enough (unlikely, given that it's the same unit as the R8 and should be near instantaneous) or there's a delay between the crank's actual revolutions and what the 'rev counter' displays on the screen. Or I'm just a rubbish driver.

I was considering the latter when I read Travis Okulski's review on Jalopnik, in which he said "There is a software issue with the tach right now, in that it doesn't accurately read redline, so you hit the limiter a lot. They are working on fixing the software."

So I asked Lamborghini's PR to confirm or deny. We're still waiting on a reply and will update as soon as we have one.

All of which might come across as an overly defensive reaction to a bit of a bashing on YouTube. But given this dash display will be coming to the new TT and, no doubt, many other 'group' products if there's a glitch you'd have to hope it gets sorted quickly. OK, so a small lag in the rev counter probably won't be an issue for most TT owners. But if it denies Huracan drivers the full 610hp they've been promised - and makes them look like hamfisted idiots if they go hunting for it - Lamborghini may have cause to feel aggrieved that Audi didn't test this before 'gifting' the tech to its supercar subsidiary.

Now, if you'll excuse me, I clearly need to get down the gym.

That's pretty poor tech form from Audi.... Lexus went all digital for the LFA after they found the the analogue rev counter couldn't rise and fall quick enough with the revs of the V10. This will be a major embarrassment....

We have a new Number One first world problem:

1. My new Lamborghini seems to hit the rev limiter rather too easily when I am spanking it around a sunny race track.

2. My personal trainer took the week off so I have to workout alone

3. My wallet won't close because there's too much money in it

4. My Brie is too hard

5. My cleaner has taken the day off

6. My wife complains that her Jimmy Choo's keep getting stuck in the grooves of the deck on our yacht.

7. My wifes underwear model friend will only have a threesome when we stay at our beach house on the Cote D'Azur.

8. The alpacas keep escaping.

9. How do I spend this big wad of £50 notes before they cease being legal tender?

10. I have three different invitations to parties at the Monte Carlo GP and I don't know which one to accept.

My pedantic side has to take issue with this:

The power band is the rev range between where peak torque occurs and where peak power occurs.

I guess a "First World" solution would be drive a Ferrari FF rather than a Lamborghini - the underwear model ( and her other friend ) can then travel with you and your wife wink

Fair one. Peak hp 250rpm before a redline you can't 'see' is an issue though.

And thank you for the top 10 first world problems too - very good!

The other possibility of course, rather than the counter lagging behind, is that it's reading right and the upchange and the limiter are set before peak power, even in corsa. That would be quite something, but how would you prove it?
You sort of hint at that as an hypothesis in the headline, but not in the story.

Dan, perhaps the question is why does the Hurucan upshift automatically at all apart from in pure "soft" mode?

Maybe because the software is not up to scratch !

What I am saying here is that when you add more and more levels of intervention you have to make sure you get them working well, or calibrated as is the in phrase.

The old C43 AMG with it's auto box just bounced off the limiter until you moved the gearshift up a gear. That's how it should be. But with paddles not gear knobs obviously.

It must be great to drive a Huracan round a sunny test track but poor 'ol "Chickenarms Trent" get's a hell of a bashing...

"I am not sure, if thic Huracan is driven by a bad test driver or his manly looking aunt!"

"I can go faster with my fiat."

"Where the hell is your safety gear? You fking lunchbox squid."


A "lunchbox squid" ?

Surely a "laggy" rev counter actually means that more drivers are likely to use MORE of the 610bhp on average, not less???

Not if you're shifting up 500rpm too early for fear of running into the 'invisible' limiter, I'd offer. Check out 1:37 in the vid for what happens then - neck still hurts!

And the First World Problems list is pure PH gold - top work! clap

Cheers,

Dan
