0-60 mph times

[Andy Gregory]

It's been well documented that the Group B cars could reach 60 miles per hour (from standstill) in about 2.3 seconds. The modern WRC machines acheive 60mph in 3 seconds, but what about the Group A cars in between.

Does anyone know the official figures for the following cars: 1987 Group A Lancia Delta HF Turbo (8 valve), 1990 Group A Toyota Celica GT4 ST165 and the 1995 Group A Subaru Impreza 555.

It'd be interesting to know.

You do know that what the motor makes ----or doesn't---the final drive can dontcha?
Then there's min weights.
Restrictors on the turbo inlet going ever smaller.

And on and on.
Very hard to say with certainty anything this or that was/is decisive.

Ever compare winners average speed on stages?
Much better idea of the overall capability of the cars than zero- 60 stuff.
What surface for example?

The Swedish magazine "Rally" uised to to 40 km/hr to 50 or 60 and on and on and 90km to110, 120, 130, 140km/hr replicating the way rallycars are run.

That would be far more interesting.

the answer would be "bloody fast" I suppose, but, as janvanvupra said there is a lot of factors involved. My guess is 0-160-0 test would be the most objective in this case.
just to give something to start with..
stock 1987 Integrale was capable of doing 6.6 to100
stock celica did 0-100 in 7.8
impreza - 6.3
imo if you shave off around 2 seconds of this figures you would get somewhere close

IMHO it is not a question possible to ask without given parameters regarding tires, the preffered gear set for the stage in question and information regarding temperature (boost pressure), humidity, stage length (fuel amount) friction, temperature of road, altitude and some other variables. I also do not know to what extent you where allowed at this time to change for example camshaft for different driving environments.
All in all it is a difficult question.

I sincerely doubt and question that the GpB cars for rallying did 0–100km/h (or even 0–60mph) in about 2.3s. The GpB cars for Rallycross did that, with more bhp, torque as well as shorter ratios and very soft slicks. Strange enough that some of the nowadays ERC cars are claimed to do it in less than 2.0s, although hampered by a 45mm turbo restrictor.

[shurik]

2.3, 2 seconds is the time of super bike acceleration.. Sound impossible for a car without slicks and drag race setup..
If I'm not mistaking, in Discovery series about Subaru team there was a mentioning about 0 to 60 around 4.6sec in 2005 Subaru :/

The cover of the Swedish magazine Teknikens Värld, issue no 21 of October 10 1984, reads:

"Schanches Escort 4WD: 0–100 på 2,5 sek!"

They did a test drive of the first ever Xtrac (Norwegian Martin Schanche's Rallycross Ford Escort XR3 T16 4x4 with its mighty 560bhp Zakspeed 1860cc engine) and pushed it nearly a quarter of a century ago already to 2.5s…

BTW, the very car is still well and competitive (for sprints and hillclimbs) and lives nowadays with its current owner Mike "Mister Xtrac" Endean on the Channel Island of Guernsey.

After seeing this video, I don't know if to believe you or what I see ... lol
