Peak output of the R6 surpasses its predecessor by 20 kW (27 bhp) with 190 kW (258 bhp) at 6650 rpm. Maximum torque of 300 N·m (221 lb·ft) is available between 2500 and 4000 rpm. The company says the basic unit has the highest specific power output per liter and the highest power/mass ratio in its class at 63 kW/L (84 hp/L) and 1.18 kW/kg (0.717 hp/lb), respectively.
That "highest specific power output per liter in its class" of only 84hp/L got me thinking of the Nissan G35's 298hp/3.498L V6 - 85.19hp/L- and the Acura TL's 270hp/3.210L V6 -84.11 hp/L- , but then I realized that the R6 numbers in this article are kind of "screwed up" by having some strange mix of DIN and SAE ratings: 190kW = 254.69hp (190/.746kW/1bhp) and 190kW/2.997L = 63.4kW/L = 84.98hp/L... and still came up short.
Nice article overall, though...

is output per liter a meaningful number in any way?

At least for me if the article is stating something like this...

SWEET ENGINE! I'm just hoping these electric pumps are reliable. Considering all these different alloys in this engine, I'm sure it's going to be very sensitive to overheating.
I wish BMW would put this engine in the E46 coupe's last year of production.

I think in the real world it does nothing for us consumers. Afterall, if we wanted more horspower or torque we can get it with other means. But I think the horsepower/L is more of an engineering achievement and is more meaningful to the automotive industry from a technical standpoint.
I think it's absolutely amazing that you can squeeze-out over 300 horses from a normally aspirated 3.2L engine and still remain within the very strict CA emission codes.
But then again, I've been told it doesn't take much to get me excited.
