Years after the BE3/6 PSA is producing a 6 speed BE and this time it's a proper compact design that is as short as the 5 speed designed in the late 70'. https://site.groupe-psa.com/powertrain/en/boites-de-vitesses/     For now the ratios are good... for a diesel.     Can you bolt a good old BE3 bellhousing? Probably ; but for a GTI you also need custom 3/4/5/6 gears.
