Turbo Lag. New RR Sport

[APOLO1]

Spent an interesting half day at Gaydon yesterday, with the new RR Sport, epic on road for comfort, very cleaver suspicion, very planted when need but S class like when required.

The biggest disappointment was the use of cheap plastics, and the price is way to expensive for the 3.0.

The spoil of the day, was the admitted FACT, that despite the amount spent on the car, they have still not sorted out the massive turbo lag on take off on the 3.0 engine….This is unacceptable today.

It's a turbocharged engine... Unless you use another method of forced induction, you will always have some sort of lag.

If you don't want lag, get yourself the Supercharged.

But there is no lag, on the cayenne 3.0 TDI, or The 4.2. For me this was a deal breaker, it so annoying at junctions. To put you foot down to go and …nothing, Its not the 4.4 TDI, just on the 3.0 TDI.

I know of no other pertrol or TDI engine that has this problum,

Just coz you don't like it, I wouldn't call it a 'Problem'... Just don't buy it.

i wont, i will wait for 4.4 tdi

[seawise]

i went for the 4.4 rather than 3.0 on the full fat RR for same reason. 3.0 is fine once you are up and running, but off the line and for 'give or take it' overtaking opportunities u need the V8 really.

That isn't technically true. Unless you are running an ALS (anti lag system), which is almost exclusive to WRC rally cars and other high end competition cars (and I'm not even sure if possible on a diesel). Then all turbo road cars suffer turbo lag.

What 90% of "jo public" do is confuse turbo lag with a thing call boost threshold. Boost threshold is the point in the revs that there will be sufficient exhaust gas flow to produce significant boost.

Turbo lag is something that happens after what is called a stall period. A stall period can happen at any point in the revs while the turbo is boosting, even at the red line.

This sounds more like some kind of electronic throttle programming than a boost issue.

I was at the driving day too (I think we had lunch together, judging by your vehilce history). Agree re the turbo lag and I was also disappointed with the 3.0's brakes which seemed to struggle with the weight. The steering was fairly vague too. Having said that, the 5.0 Supercharged version had incredible dynamics.

Afternoon, Sorry I shot off, had to get back. Birthday party.

The brakes were not too bad in my view, not in the same league as on the Cayenne. I agree that they struggled with the weight of the car.

With regard to the above post, The RR Sport is the only car turbo or none turbo that has this take off problem, I gave never experienced this in any other car, ever, it gets worse with miles.

Shame the 2.7TDV6 was utterly terrible at this, the 3.0 MY10 Sport we owned was a revaluation by comparison, So how does it compare with the outgoing 3.0? Shame, gone off the new stuff from JLR. (Aside the FFRR )

[hornbaek]

I changed my 09 TdV 8 for a Sport in the Spring and the turbolag (or whatever it was) infuriated me so much that i sold the car 8 weeks later for a TdV8 Westminster. Much better car in my opinion.

[APOLO1]

I wanted this car to be good. The turbo lag is really bad, and in my experience it gets a whole lot worse with miles, When I asked about this I was told yes we know, If you want to see what a good 30 TDI engine is like call in at any Porsche dealer there are 38 of them in the UK and ask for test drive in the 30 Cayenne, ok the style is not to every ones tast, but engine wise its in another dimension….Massive mistake from RR not to sort this problem.....massive, the car is crap in my view until this is sorted

I don't think it's turbo lag, it's the entine and transmission management software. My D3 is slow to wake up if left in D - not least because it defaults to starting in 2nd - better in Sport and pretty sharp in Sand Mode.

In other news, why no TDV8 RRS?

TDV8 in the new year for the RRS

Having driven the new SDV6 Sport i'm confused as there was no lag in either of the cars that i drove.

Slight gearbox delay perhaps but no lag.

Fair enough: Car more or less crucified the SDV6 they reviewed on the basis that it didn't have the performance of the X5 or Cayenne - and made no mention of TDV8. Seemed odd.
