3rd paragraph:"A dual-scroll turbocharger...". Turbos dont have screws like Roots-type superchargers. They're turbines and thats about it. Either GM needs to get a new technical staff or Supercars has to stop editing articles. The car is turbocharged. It runs on exhaust gasses and not on the engine's crank. It has dual cam timing, something Hondas have had for years (i-VTEC). Direct injections is also something thats been used in Hondas (racecars, mostly) for some time now to keep/raise power levels and still get better fuel economy. This really isnt anything new. its just GMs offering to try to counter Mazda's ever popular Miata/MX-5.
