Be Nice - Rookie TDI questions

The lady and I test drove an 06 Jetta TDI tonight and need to know what they are like...

Understand - she's coming out of a NICE Lincoln LS V8,
but our first impression of the TDI where:
suprisingly quiet
little stiff on the ride
but nice....

4 door - 6 speed tiptronic auto - pleather - sunroof - heated seats, splash guards.... rated @ 42 Hiway....

list for like 24900 and he said 23900 first cut....
told him I first had to come ask "youse guys" and ya'll too


What's the story on them ?

The Wife liked it...

05/05 4x4 EB Excursion -gone but not forgotten SCT enabled 1/8th 8.9 seconds....

I don't know anything about the new auto that they have. I was looking at Edmunds.com the other day and noticed there isn't a whole lot of mark-up in Jetta's comparing invoice to MSRP.

My gut feeling is fuel is going to return to $3 per gallon before summer which will drive these TDI's to command 'over sticker' pricing again.

My opinion is go for leather vs pleather when it comes to resale but that's up to you.

Andy has it right in my opinion. With leater (package 2) you get a bunch of computer stuff, and its not much more. Word is the auto will get better fuel milage on the Highway, due to the higher 6th gear. But city driving the auto will get into the 30's where the manual can keep you in the 40's...

I average 43 with the stick... but the winter has ulled me down quite a bit... 47-49 hand calculated is not out of the realm at 70 mph on a long trip... Speed does not effect my fuel milage that much ( not like the truck)

I love mine.... but its not a lincoln...

Being geeked up on cetane booster gives me +4 mpg @ 85 with the A/C and cruise on.

Even with my mods I'm in the upper 30's @ 81 with the A/C and cruise on.

Please allow me to clarify:

Actually, an increase in speed has EXACTLY the same net affect on economy on both a Golf/Jetta/Beetle TDI and a F350 PSD or a 9900i at 80,000#.

The calculation for air drag is 1/2(Cd) x (area) x V^2.

Since we do not change the Cd, or area, it can be said that the air drag is related to the SQUARE of the speed (velocity).

For a given vehicle at 55 MPH, V^2 = 3025. Now at 65 V^2 = 4225, a change of 30% GREATER drag, with a 15% increase in velocity.

Another way to think of this is that for every 10% increase in speed, you increase drag twice that, or about 20%.

Of course, this does NOT take into account economy differences due to engine RPM, and that can be HUGE. Which I think is what he ment.
