We once had one of those bosses who would, for the smallest oversight or infraction, growl, stiff-spined and red-faced, "No, no, no, [expletive deleted] no!" Pretty much all of you responded the same way after discovering our test-track results for the 2010 Buick LaCrosse CXL with its direct-injection 3.0-liter V6. Come on, guys, you've got it all wrong. A 2-ton Buick powered by a 255-horsepower 3.0-liter V6 that gets to 60 mph in 8.4 seconds (8.1 seconds with 1 foot of rollout like at a drag strip) is not a car that General Motors needs to make apologies for. But OK, you're in full denial mode about the 2010 Buick LaCrosse. We've given you all the recognizable markers to compare cars when they're speeding along at their dynamic limits, but we haven't been able to program our satellite-based VBOX testing equipment to judge how serenely a luxury vehicle glides to a halt.
