Volvo S40 (P1)

• Second generation S40
• Four door sedan based on Volvo P1 platform
• Sold in the USA from mid-2004 through 2012 model year
• USA models were equipped with 5 cylinder gasoline engines
• USA normally aspirated models had a 2.4L engine, FWD and manual or automatic transmission
• USA light pressure turbo models had a 2.5L engine, FWD or AWD and manual or automatic transmission

The second generation S40 was introduced in mid-2004.  This caused some complications as Volvo already had a completely different version of the 2004 S40 (NedCar) in showrooms.  It was too early in the year to label them as 2005 models, so many localities labeled these as 2004½ or 2004.5 model year vehicles. Some DMV systems couldn't handle this mid-year model distinction so they ended up registered as 2004 or 2005 model year.  This can cause some confusion when trying to find parts and accessories for 2004 S40 models since both versions of the S40 completely different.  It definitely would have been easier for everyone if these cars were all registered as 2005 models.

At IPD, we tend to just label these late 2004 models as 2005 models to avoid confusion with the earlier S40.

This was first vehicle built on Volvo's P1 platform.  This platform is also used in the Volvo C30, V50 and later C70 models.  The P1 platform was jointly developed with Ford and Mazda (Ford calls it the C1 platform.)

All USA P1 S40 models have 5 cylinder gasoline engines offered in 2.4L normally aspirated and 2.5L turbocharged variants. Manual or automatic transmissions were available as was an AWD option for some years.

Model information is based on the USA vehicle market. Other model variations may exist outside the USA.
