ADDITION: Shout! Factory - Region 'A' Blu-ray - December 2015': I don't see a lot of difference from the 2013 Arrow 1080P transfer - the Shout! Factory is more technically robust and the colors may be marginally richer.

Shout! Factory's Audio gives the DTS-HD Master options in 5.1 and 2.0. The bump as a few separations and both are fairly deep for the film's bountiful car-related effects.

We lose the Arrow commentary but gain “Mystery of the Car:” a 9-minute interview with producer/director Elliot Silverstein, "The Navajo Connection:” an interview with actress Geraldine Keams lasting a dozen minutes and “Just Like Riding a Bike:” spending 12-minutes with actress Melody Thomas Scott. There is also the usual theatrical trailer, TV and Radio Spot plus a stills gallery.

I'd give a minute edge to the Shout! Factory in the a/v department but the UK package has the much stronger extras with the commentary, booklet, case and interviews. The Car grows on you - perhaps because you more easily forgive its weaknesses. Perfect as the 'B'-opener for a late Friday film night. Depending on your requirements and pocketbook - either may suffice.

ADDITION: Arrow - Region 'B' Blu-ray - July 2013': The superlative new 1080P transfer from Arrow breathes new life into The Car when compared to the 5-year old, flat SD release. The comparative captures identify the upgrade - passive but more layered colors, depth, superior contrast exporting a more film-like appearance. There is a touch more information in the frame - in the top and left edges. Skin tones cool to a more natural state and it looks sharper. This is dual-layered with a high bitrate and is a solid transfer.

Audio is in an authentic linear PCM stereo track at 1536 kbps. It sounds quite buoyant with the many effects exported with some depth. The original score is by Leonard Rosenman who has done a fair amount of TV work. It seems well supported by the lossless transfer. There are optional English subtitles on the region 'B'-locked Blu-ray.

Arrow include some new extras - an audio commentary with director Elliot Silverstein (A Man Called Horse) moderated by Calum Waddell, a 28-minute featurette entitled Making a Mechanical Monster which has Special Effects Artist William Alridge remembering The Car. Hitchhike the Hell has 10-minutes with actor John Rubinstein discussing his stint of becoming a victim of The Car. We get an introduction and trailer commentary by director and The Car fan John Landis and the original trailer. The Blu-ray package has a reversible sleeve featuring original and newly commissioned artwork by Joe Wilson and inside is a collector's booklet featuring new writing on the film by Cullen Gallagher as well as a brand new interview with co-writer Michael Butler conducted by Calum Waddell, illustrated with original archive stills and artwork.
