Very interesting - I've never seen before the car on these photos, called Lada Samara S-Proto, but it seems to be very similar 1987 Lada Samara Eva, designed and built by little company VFTS from Vilnius (Lithuania), that was managed by famous Soviet rally driver Stasis Brundza. And as far as I know Eva was not rally, but touring car! The engine, based on a standard 2108 1S-litre block, had increased to 1860 cc capacity, fuel-injection, turbocharger, new cylinder head with two camshafts and four valves per cylinder, produced 300 bhp and was placed behind driver's seat! The rear-wheel drived car weighted 980 kilo (2160 lbs) and only looked alike its front-wheel drived prototype (Lada Samara) - in fact it was fiberglass bodyshell on the tubular space frame. I guess, Lada Samara S-Proto was created as a further development of Lada Samara Eva and it was doubtless a rally car (must be really Group S), like most other cars made by VFTS. Sorry, but it's all that I can say.
