Its one of the main reasons that BMW 5-6 years ago went from a twin-turbo arrangement in their N54 6-cylinder in-line engine to their current N55 engine which is single twin-scroll. BMW have just announced this N55 engine is being replaced with their new B58 engine which retains the single twin-scroll turbo arrangement. Which is my way of saying the apart from the absence of direct injection which the BMW engines do have, Volvo's T6 engine is in pretty good company.
And just for the record, the T6 engine was designed by Volvo, but it was actually built under contract by Ford in their engine plant in Wales. This OEM arrangement was an artifact of the years when Ford owned Volvo. The Welsh plant also produced the late and unlamented 3.2, the non-turbo version of the same six-cylinder engine. Whereas the T6 was largely bullet-proof, its 3.2 stablemate had a long and increasingly more troubled history of high oil consumption. My cars were apparently wholly typical in that regard: my trouble-free 2012 XC70 T6 was acquired as a Volvo-subsidized dealer swap when I dumped my 2010 V70 3.2 after a year and a half because of an unrepairable oil consumption problem.
