Alfa Romeo MiTo Quadrifoglio Verde at Frankfurt

Alfa will be bringing the 170bhp Alfa Romeo MiTo Quadrifoglio Verde to Frankfurt Alfa Romeo has revealed that they’ll be bringing the  MiTo Quadrifoglio Verde (MiTo four leaf clover) to the Frankfurt Motor Show next week, featuring a 170bhp Multiair engine as we reported back in June (goodness, we’re ahead of the game sometimes!). The ‘Quadrifoglio’ bit refers back to Alfa’s racing history, and was the emblem used on those cars and was most recently seen on special editions of the Alf GT and 147.

Bedford Autodrome to get Ariel Atoms for 2012

Corporate track-days at the Bedford Autodrome will get lairier in 2012 - Somerset-based Ariel has announced it’ll supply ten cars for the PalmerSport track-day events next year. Stopping short of the unhinged Atom V8, the PalmerSport-spec cars get the normally aspirated 245bhp Civic Type-R engine, and some key changes to set it aside from the Joe-Public Atom. The Palmer-spec car will get a Sadev paddle-shift sequential gearbox, which swaps ratios in 60 milliseconds, whilst some choice chassis mods optimise the Atom for its full-time track-toy brief.
