BMW's new M engine needs a better voice

BMW's M division claims its new twin-turbocharged 3.0-liter inline six-cylinder engine is every bit as good -- if not better -- than the glorious, naturally aspirated 4.0-liter V8 powerplant it replaces in the new M3 sedan and M4 coupe.

Just weeks after announcing its Polestar performance kits for the T5-engined cars, Volvo is now offering packages for the XC60, S60 and XC70 models fitted with its turbocharged six-cylinder engine. The T6 Polestar software package adds 25 hp and 30 lb-ft of torque, bringing totals to 325 hp and 355 lb-ft, respectively.
