Tax or fiscal horsepower is a non-linear rating of a motor vehicle for tax purposes. [19] Tax horsepower ratings were originally more or less directly related to the size of the engine; but as of 2000, many countries changed over to systems based on CO 2 emissions, so are not directly comparable to older ratings.
In 2011, Super Chevy Magazine conducted a chassis dynamometer test of a well documented, production-line, stock but well-tuned L-72 "COPO" Camaro, and recorded a peak 287 hp (214 kW) at the rear wheels, demonstrating the substantial difference between 1960s-era SAE "gross" horsepower ratings and horsepower at the wheels on a chassis dynamometer.
The 1965 4.2 XK fitted to the carburetted E-Type had a listed output of 265 hp (198 kW) SAE gross; the 1986 fuel injected 4.2 XK fitted to the series 3 XJ6 was listed at 202 hp (151 kW) DIN net.

The article claims power output of 440-460 horsepower, instead of 375 as advertised. Is this SAE Net or SAE Gross? JDS2005 01:47, 3 February 2009 (UTC) The 450 horse your hearing is what the TRUE 429 Super Cobra Jet, horsepower ratings. They were considered unoffical.
As is the case with all pre-1972 American passenger car engines, published horsepower and torque figures for those years were SAE "Gross," as opposed to 1972 and later SAE Net ratings (which are indicative of what actual production engines produce in their "as installed" state - with all engine accessories, full air cleaner assembly, and ...
The factory-quoted horsepower rating of 245 bhp (183 kW; 248 PS) was measured using the SAE (gross) system current in the USA at the time the 420/Sovereign was sold there. The SAE (gross) system excluded many accessory drives and often used non-standard induction and exhaust systems and so was replaced by the more accurate SAE (net) system in ...
A high-performance 327 cu in (5.4 L) variant followed, turning out as much as 375 hp (280 kW) (SAE gross power, not SAE net power or the current SAE certified power values) and raising horsepower per cubic inch to 1.15 hp (0.86 kW). From 1954 to 1974, the small-block engine was known as the "Turbo-Fire" or "High Torque" V8.
At first the RAC rating was usually representative of the car's actual (brake) horsepower, but as engine design and technology progressed in the 1920s and 1930s these two figures began to diverge, with engines making much more power than their RAC ratings suggested: by 1924 the 747 cc (45.6 cu in) engine of the Austin Seven (named for its 7 hp ...
