11.000 visitors! Thank you! This milestone deserves something seriously cool. How about supercharged Fiat from the 70's with Bertone styling and Abarth race spec?

This very special thing basis on not so special Fiat 131, predecessor of Fiat 124, maybe better known as Lada. Well, basic dull car can turn something beautiful when racing department takes over. Abarth founded 131 suitable for their next rally weapon, because the large engine room, rear wheel drive, and roots in 124 that was familiar from earlier rallies. Development started somewhere in 1974 and deadline was set to 1976 season. Many prototypes was developed, were wildest one is 131 SE031 Abarth equipped with tweaked Ferrari Dino's V6 engine producing 270hp@6800rpm! After several prototypes best engine combination was chosen to be 2 litre twin cam with supercharger that was suitable for group 4 in world rally championships. Luckily, homologation for the group reguired 400 road legal units to be produced.

Boxy style beats organic lines every time. Source: 131abarth.com
Boxy aerodynamics are designed by Bertone and are able to swallow even 12 inch wide rims for tarmac use. Works car had 12/10 inch rotors with twin calibers, hydraulic hand brake, three different body strength options, and ZF's five speed gearbox with limited slip differential. The KugelFischer mechanically injected 1995cc engine produced around 220hp@8000rpm and rev limiter was set all the way up to 8500rpm! Cool figures for car weighting just 973kg.

VW Beetle RSi Cabrio '2003

'Ladybird'
Source: cyberbeetle.de
Ladybird -comes to my mind when thinking about 1st generation new beetle, it's maybe the most playful car ever made, especially the cabrio. Design is caricature of rounded car, were the another option would be boxy Volvo 700 from the eighties. Shape doesn't respect the original, but it's easily discovered as Beetle, because there's no another design that comes even close to Beetles characteristics. But there's nothing playful of driving the car, except the smiley faces of people questioning your libido and sense of style. Yes, it's just another Golf with fulsome retro styling and safe, but not thrilling driving experience. Luckily, Dub guys saved some mushrooms when drawing the lines and decided create the RSi -version to boost the sales and make New Beetle behave according to cartoon appear.

Formula is familiar among Wolf Cars. Take the basic chassis, install powerful lump (from the Golf R32 and originally from TT), ensure safety with four-wheel drive, tweak exterior and interior and vòla wolf car it is! With this limited edition of 250 units the exterior and interior styling is exceptionally successful with the wide body, huge wing, and tasty orange leather interior with carbon detailing. I have never driven RSi, but according to press added aggressive didn't help and RSi don't drive like it should, even there's rumours that Porsche was involved in chassis design. Introduced RSi cabrio is ultimate version of the RSi and only couple "design studies" was ever made and unluckily without the tasty orange interior.
