Lands End-JOG...Fastest possible production car?

[Wacky Racer]

Hypothetical question:-

Assuming two drivers in one car...(So one can sleep whilst the other drives)

No other cars on the road, you have the complete UK network traffic free to yourself.

Any car will do, your choice, money no object.

You cannot use any motorways, but you can use dual carriageways.

The 70mph speed limit does not apply, you can go as fast as you like.

You are not racing against anybody else, it's just you (and your co driver) against the clock.

What car would be best for the job?

How long would you reckon it would take?....remember NO motorways....



EDITED TO ADD:-

With motorways as well as without.

For the purposes of the exercise factory fitted speed limiters are disabled, but the car in all other respects should be 100% standard.

I reckon about 10 hours, I think to average more than about 80mph would be difficult, even with clear roads if motorways are banned.

As for the car, any 250bhp+ car probably best to have 4 wheel drive. I doubt you'd gain much with a hypercar. A well sorted Scooby or Evo for example.

[DocJock]

Outrun 2003 was won in just under 9 hours, but that involved 130mph periods on motorway most of the way.

I'd say 10 hours would be optimistic.

[marmitemania]

Surely if you are going to be able to average 80 MPH at most I would have thought fuel economy would come into play, you will loose all you're time and more gained in a high performance car with the more frequent fuel stops you would need.

Something diesel, powerful and with a big fuel tank.

535D maybe?

[W00DY]

Chipped/de-limited Phaeton V10 TDI.

Inconspicuous, fast, comfortable and a decent range.

Sub-11 should be do-able given that if we consider speed limits don't apply then false/concealable plates would probably be necessary . What's the mileage n a non-motorway run?

Didn't see traffic free part which makes it a bit of a rubbish hypothetical really.

With a completely empty road network at your disposal, I think it could be done pretty quickly. There are significant stretches of dual-carriageway and even single carriageway roads that you could average well over 150mph on in a suitable car if you were absolutely certain there would be no other traffic around (dual carriageway vs single carriageway is slightly less important if you can safely use both sides of the single carriageway road).

I think I'd probably choose a Veyron - ultimate handling isn't really the issue, you just need something capable of munching miles of mostly straight roads at a stupid rate without tiring you out too much. I think 10 hours should be doable.

Suspect you'll be stopping every half hour for fuel with the Veyron. As above, a pokey diesel for me.

Several fuelled up Veyrons?

Which diesel though? A big part of the run will be limited by top end speed (perhaps not actual top speed, but the ability to accelerate from 180-220mph on a few miles of straight dual carriageway) and aerodynamic stability, I think you'd need your diesel to have a top speed around the 200mph mark at an absolute minimum.

Relay! Like it.

[MJK 24]

I did it in 12hrs 12mins having a sensible drive from JOG down to LE.

[rouge59]

The correct answer to this question is, of course, a 911 Turbo.

Panamera, Alpina D3? Wasn't there an R8 diesel or am I imagining that?

[Kawasicki]

Something with big power, 1000bhp or more, giant acceleration and brakes that won't fade. Maybe a veyron, with additional fuel tanks, and gearing changed to give a max speed of only 220mph.

The R8 diesel never happened (it would probably be the right answer if it had been made). Neither of the other two is actually very fast in a straight line; I'm not aware of a production diesel capable of over 170mph?

Given that it's closed roads, something like this;



Might stretch 'production car' a bit I suppose.

[Wacky Racer]

Remember the car has to be a STANDARD production car....

Not Chipped.

No special tyres.

No added fuel tanks.

As it came out of the showroom.

I think you missed the key one - without the speed limiter removed. That basically removes anything mainstream and German from the equation because nothing limited to 155mph is going to cut it.

[Wilmslowboy]

AA route planner says ....956 miles and 19 hours (non motorway)

A 991 turbo S or LHD 991 GT3 (which comes with the option of a 90 litre fuel tank)

I think you could possibly do it in 3 fuel stops (4 tank full) in the GT3 and 4 stops in the Turbo S ....(c12 mpg)

In the late 50's the average speed on the Milli Migla was 103 MPH....I would except a well driven turbo s should be able to achieve 125 (if not a lot more), 10 minute stop/ driver changes - should see it done in 8 hours.
