Švédský jezdec začal svou kariéru v týmu SAAB. Bohužel brzo se ukázalo, že jsou švédské vozy na nejvyšší úrovni nepříliš konkurenceschopné, a tak se tým z mezinárodních rally stáhl. Pro Blomqvista to znamenalo začátek prudkého kariérního postupu, který vedl přes Talbot až do Audi. První sezonu Švéd absolvoval jako testovací. Během tohoto roku však stačil svým jízdním stylem uchvátit všechny šéfy a inženýry od Audi - do té doby nevídané brzdění levou nohou umožňovalo projíždění zatáček řízeným smykem a mnohem vyšší rychlostí, než bylo doposud zvykem. Stigova rozevlátá jízda byla také lákadlem pro diváky. V roce 1983 byl Blomqvist nejrychlejším ze všech jezdců Audi, bohužel velké množství technických problémů mu umožňovalo blýsknout se pouze dílčími výsledky.

Blomqvistův čas však přišel o pouhý rok později. Audi relativně rychle vybojovalo titul mezi značkami a ve zbytku sezony se mohlo věnovat plné podpoře švédského jezdce v souboji s Finem Markku Alenem od Lancie. I přes heroický výkon svého soupeře však Blomqvist dokázal využít všech výhod Quattra a dojel si pro zasloužený titul.

Po skončení éry skupiny B se Švéd několikrát objevil na startu Rally Paříž - Dakar. V devadesátých letech také započala jeho spolupráce s českým týmem Škoda Motorsport. S kitovou felicií absolvoval britský šampionát, rok 1996 zakončil fantastickým třetím místem absolutně na RAC Rally. Českým barvám zůstal Blomqvist věrný i v době nasazování Octavie WRC. V poslední době jsme legendárního Švéda mohli několikrát vidět za volantem produkčního Subaru.
