Hi,
Here is the C70 model year changes list so far... Hope this line breaks okay ;-) thanks Chris, Charles, Jeff, recollections from others, and folks I have talked to in past, bt can't recall names.... Any comments welcome here or offlist abdj@rmi.net
Carl
DRAFT C70 model year differences. This is a mix of opinions, much of which can not be substaniated (disclaimed enough?)
Options:
Premuin Leather that is thicker. Door panels have stiched leather around latch.
Misc
First models were called ‘Prestige’ . There is a C70 Prestige spiral bound book describing C70. (Exact conents not known)
Interior changes:
1. In 99 glove box door latch changes from Chrome finish to black
2. In ?2001 Wood replaced with simulated wood.
3. Europeans offered two tone leather (white/blue, black/brown, Red/??)
4. Europeans offered wood inlaid steering wheels.
Exterior and body changes
1. Rear side windows differ after 1998.There has been a retro fit campain going on by Volvo for the 1998 C70s related to the rear side windows. The work entails converting from the hinge setup to a 3 bolt setup. The change was to correct a problem with water leaks that develop around the original hinge bolt that goes through the glass. In heavy rain or through a car wash water ran into the car from around the hinge bolt. The change was not related to windows popping out or anything else like that. (Charles)
When my "98" C70's Rear windows were replaced, the seal and window were replaced, with a different type of seal and a larger rear window the “fix” the leaking problem that didn’t exist. Once replaced, the left rear quarter window, started to leak. That leak was fixed by a tech disassembling that window again and cleaning the seal & resetting the window. The latches were never replaced the hinge is part of the window. (Chris)
2. Side blinker lights replace Volvo emblem in ?1999.
3. Rumored increase in body stiffness in 1999.
4. Color selections change.
1997? Coral red, black, White, Casis (purple) Safron.
1998? Red, Black, Silver, Safron, Casis
1999?
2000?
2001?
Wiring/Electrical
1. Wiring moves to multiplexed system decreasing wire harnes complexity and weight. (True on V/S series, also on C?)
Engine/Transmission
1. Engine management system changed from Bosch to Seimens in 1999. Prevailing view is performance loss occurred too. The throttle is “drive by wire’” replacing throttle cable. Volvo uses VADIS system used to download software. The emissions are cleaner.
2. Engine intake manifold takes new shape.
3. Engines cam has lesser duration to increase low end torque, decreases high end.
4. Engine is distributerless.
5. Engine top mount changed from steel with cutouts to cast aluminum in 1999 (cheaper)?
6. TRACS from 1998 changes to Stabiliy Control (STC) in 1999+. STC works at all speeds limiting throttle, whereas TRACS works at about 30mh and less using braking.
Tech View of C70 (opinion)
P.S. Volvo Techs dislike working on C70's, because of either inconsistencies of being hand built, or the differences between other Volvo models. And then, finally also because when there is something wrong, its usually time consuming and difficult to fix.
So again many of the changes between newer C70’s and older C70’s was to allow Volvo to maintain a consistency with the regular 70 series, Also Remember that the earlier C70s were being build “By hand” at the TWR owned and controlled factory, After the Strike Volvo cars took greater control and started to standardize the production…
Marketing and market Positioning of C70
For those of you who have been around for a few years, you’ll remember the C70 was marketed and intended to be a limited production Touring Coupe, for empty nesters who wanted to make a Statement. If you don’t believe me, look at the original sales education pamphlets (not the sales brochure) and Look Up any of the older Rolling or SEES magazine along the URL for the C70 Factory, I’ll supply the URL latter when I can remember it.
