Top Gear Acceleration Times

I'm having a discussion with a guy over on Vortex and I've been touting the top-gear acceleration performance of the TDI over the 2.0. He claims the 2.0 has better top gear acceleration. Who's right?

I don't want subjective, kick-in-the-butt feel. I'd like hard numbers, say 50-70 or 50-80 mph passing times in top gear. I did a search last night but nothing turned up. Car and Driver did a short take on a NB TDI and compared it to the 2.0 but only did 0-60, 5-60 and 1/4 mile (in which the 2.0 was only quicker by a very tiny sliver).

Anyone out there with hard data?

Plane,

The review from the post: "TDI Review from South Africa's Topcar Magazine" claims the TDI will accelerate from 80 km/h to 120 km/h in 12 seconds in top gear. The author seemed impressed so I imagine this is a decent time. I'm pretty sure they have the same engine we have (90 HP). Not sure about times for the 2.0 but the GLX V6 is mid-9 seconds according to Car and Driver. I would be surprised if the 2.0's time was less than 12... the RPMs on that car (2.0) are quite a bit higher than the TDI at 50 - 70 MPH in 5th but I don't think you'd get into the meat of the torque curve until 3800 - 4000 RPM.... seems like it would take some time from 50-60 in 5th in the gasser.... where in the TDI you're pulling pretty good all the way from 1900. I'll keep looking around for actual times....

That astute organ Diesel Car quotes times of 7.7 secs for 30-50 in 4th and 11.5 secs for 50-70 in top gear for a 90hp TDI Golf. The only gasser times quoted are 6.4 and 9.2 respectively for a 1.8T Golf.

Interestingly enough they quote 5.6 and 7.2 respectively for my PD115 and I guess the latter figure is in 6th.

An alternative to actual driving numbers would be to check the engine torque/speed curves. You could probably compare the Golf with a TDI to one with a 2.0L if the gearing is accounted for.
So for the speed range of 50 to 80 mph see what the wheel torque would be (account for gearing).
The engine with higher torque wins!

Thank you gentlemen.

I found data on the 2.0 Golf GLS at the Car and Driver site. Combined with the Diesel Car figures for the 90 hp TDI, the picture looks like this for bone-stock, out-of-the-box cars:

30-50 mph
TDI=7.7 sec
2.0=9.9 sec

50-70 mph
TDI=11.5 sec
2.0=10.6

So if you pick a fight with a 2.0 at 30 mph, by 50 mph you'll have a 2.2 second lead on him. The 2.0 will get from 50-70 in less time, but if the fight was picked at 30 mph, it will only catch up 0.9 sec of the TDI's 2.2 sec lead. In other words the 2.0 is in the dust by then. Which pretty much confirms most of our experiences with street starts. Torque Rules!

Oh, and while all this is happening, the TDI driver is listening to the subtle textures of Gregorian Chant on the stereo and appreciating every nuance in the monks' voices. The 2.0 driver can't even hear heavy metal above the din!

I wonder what the times are for an upsoluted tdi. Im willing to bet its right up there with the 1.8t. The poor 2.0 gasser wouldnt even stand a chance against an upsoluter.

Couldn't find anything at vw.com... strange....

From the SEAT site: (http://media.seat.com/en/index.html)

204 HP VR6

Performance:
Top speed (km/h) 235
Acceleration 0-100 km/h in V (s) 7.3
In-gear acceleration (V) 80-120 km/h (s) 9.0
In-gear acceleration (VI) 80-120 km/h (s) 11.5
Acceleration 1000 m (s) 28.2

Fuel Consumption:
Urban cycle (l/100km) 15.5
Extra urban cycle (l/100km) 8.2
Combined (l/100Km) 10.9


150 HP P-D

Performance:
Top speed (km/h) 215
Acceleration 0-100 km/h in V (s) 8.9
In-gear acceleration (V) 80-120 km/h (s) 9.0
In-gear acceleration (VI) 80-120 km/h (s) 12.0
Acceleration 1000 m (s) 30.0

Fuel Consumption:
Urban cycle (l/100km) 7.0
Extra urban cycle (l/100km) 4.3
Combined (l/100Km) 5.3

Virtually the same performance with TWICE+ the fuel mileage.

I can guarantee you this, either of my TDIs will blow the doors off an 2 liter gasser in high gear, no doubt about that.

Skypup, you are on save ground - you will never race a souped up Lancia Delta Integrale Sedici or a Mitsubishi Lancer Evo VI. Even those Subaru WRX´s are tough to keep behind you

Ok, unfair, all turbos - How about Renault Clio Williams or Opel Astra OPC ?

There will ALWAYS be a faster one out there ...

I have to say that Im very much impressed with the top end acceleration of my Golf TDI
For a 90 hp car it will get out in the passing lane and do its job. Ive out run my brother in his Escort ZX2(130hp) from 90km/hr up to 175kmhr. The escort fuel cuts at 165. Granted now the TDI still feels dog crap slow compared to the Supra but hey I also get more than twice the milage and dont get sidways when I hope on it @ 90km/hr. This little car has really grown on me.

01 Golf TDI (the fuel miser)
84 Supra (T04 with 18+psi)

Nice numbers.

I love getting ahead of anyone in a traffic when I see a block coming up in my lane that I need to make a lane change so I don't have to slow down to allow the car next to me to pass. Several time I can see that the car next to me tries to prevent me from doing so. Well, better luck next time sucker!

The best part is that you don't get the kick-back feeling when you step on it. It nicely takes you up there. The speed goes up as the tach slowly increases. I love that!

A buddy of mine who is a VW tech took my Upsolute powered TDI for a spin for the first time and he was "Upsolutly" giddy about the performance! He kept saying a TDI should not perform like this as he broke traction into 2nd gear without popping the clutch. He could not believe how the engine just revs and revs, like a gas engine he said!

I asked if it is quicker than his 2.0 Beetle he shook his head and bowed to the power of the TDI, "HECK YEAH" he said "you can feel it throw you into the seat!".

If any 2.0L tries to pass me "I'll open up a can of Whoopass on him" LOL

Over on Vortex they never give the TDI any respect. As much as they like to bash the 2.0L the TDI gets it even more. Two seconds slower to 60??? What do you expect from 90HP?[Too bad they closed the thread.]
