Re: anti chav

Yes, and it's not worth speeding in Switzerland either. In the spirit of rec.mods I'd consider takign the limiter off, it's supposed to be capable of 183ish without the limiter. But in the spirit of staying alive and not getting on the wrong side of the insurer, it's staying as it is. It's impressive to drive at that speed on a motorway, the horizon just sort of leaps towards you.

Do it while you can, I couldn't repeat the trip to Heidelberg anymore because long stretches of the road are now marked at 110km/h and the Krauty cops are severe on those who break the law.

Yes, the tunnel was closed so we had to go over the top. It's a long, long uphill struggle and it was 3mpg from the motorway turn off to the hoighest point then 9999999999.9999999999 mpg all the way down. Average for the entire route over the pass was 23mpg. Stonking route to take, but only useable in summer it was still closed in April because of snow.

It's all dependent on the drive.

I get exactly the same economy as Richard from my TI on the work commute (250-ish miles from £42 tankful) - but on a steady 80mph motorway jaunt, I can see almost 400 miles from the same tank.

Hmmm. I don't believe you. About the economy, I mean. Driving at a constant 55mph, with no hills or head wind, the XJR will just manage 29mph. At a constant 70mph it drops to 26.5 At 155mph it should give about 5.5mpg. The 3mpg at WOT up ST Gotthard sounds about right.

That's terrible. I mean, really, _really_ bad.

Just filled up the 155 with about the same amount (yes, £42. 50.5-ish litres). Mileometer was showing 360-ish miles at that point.

Yebbut, Nom has a 200Hp engine, and uses about 170 of those, from what he has previously said, quite frequently on an 8-mile run. The 155 has a 150Hp (?) engine, and probably produces peaks of 125-130ish relatively infrequently (on a per-mile basis) on your 60-mile commute.

Given the relative journey lengths, relative power outputs and so on, it isn't really surpsing that the Ti uses more fuel. By all accounts, the T- series engine isn't particularly innefficient - the extra urban (55mph) figure is quoted as 40.4mpg.

There's also my sitting in traffic for the last 2 miles of the journey in and 2 miles out, and the bursts to well into the 'VVT Zone' for overtaking on the A-road. It's not a gentle cruise down a dual carriageway.

Less than 22mpg when commuting is pretty bad. I wouldn't expect that from any 2lt car. FFS, you could use a car with a proper engine and get that kind of mpg out of it.

Er, no it's not.

It's markedly better than a few other performance car drivers I know of (Mazda RX7, MR2 Turbo), and not actually much worse than the 2.0 8v Pug 405 I had before (that did about 280 miles to the £42 tankful, on the same journey).

The Rover Turbo lump is pretty good - the official figures make it MORE economical than the 623 with it's 150bhp 2.3 NA engine...

Er, read my post again ! My 200bhp engine is quite capable of 400 miles from said tankful, on a steady run.

Course it's not.

It's :

A. Only an 8 mile run B. Done from cold, both directions C. Contains plenty of overtaking D. Contains plenty of national-speed-limit-roundabouts (so slowing to bugger-all from 80mph or so, then accelerating back up again) E. is 50% bendy country lane

etc. etc.

Er, it has a Turbo :)

Um, it's already got about 220bhp. What do you propose I use instead ?

mpg is just fine thanks. On a steady 80mph drive, I can get 400 miles from the £42 tank. My calculations make that about 36mpg...

Heh - £42 went into the 405 when i filled it as well, used to see about 300 miles :D

Is no-one capable of making an economical engine anymore?

I don't pussy foot around in the 155, and still get over 30mpg most weeks. Worst I've seen was about 27 when I spent a week thrashing it.

Well modern engines are MORE economical than their older counterparts :)

Yes - that's cos it only generates a piffling amount of power.

If it made the same ~220bhp as mine, then your MPG would be vastly lower :)
