An interesting match-up by our sister publication Motor pitted Audi’s four-seat 4x4 against Porsche’s 2+2 tearaway. Could the prestige of the Porsche name and the purity of the £27,547 944 Turbo justify its extra cost compared with the more versatile Quattro, significantly cheaper at £24,204?
There was some common ground: both had single-overhead-camshaft engines, mounted in line, and used intercooler KKK turbochargers to boost power. The Audi’s 2144cc five-cylinder unit had a smaller swept volume than the Porsche’s 2479cc four-pot and ran a lower compression ratio (7.0:1 versus 8.0:1) but offset that with a slightly higher boost pressure (0.8 versus 0.76bar).
The net result was that the Porsche had 20bhp more than the Audi’s 200bhp, but more telling was its 33lb ft superiority over the Audi’s 210lb ft. However, the Audi used shorter gearing to enhance its inherent tractive advantage, as Motor found during its performance tests.
“With scarcely a chirp from its tyres, the Audi blasts up to 30mph in just 1.8sec – equivalent to an average acceleration of 0.75g. The Porsche, with smoking rear tyres, takes half a second longer to reach the same speed, and that on a dry, grippy surface,” wrote Motor.
“But the Quattro’s advantage is shortlived once the Porsche’s wheels have stopped spinning. The 944’s long second gear takes it up to the 60mph yardstick in a cool 5.9sec.
“From there on, it is plain sailing for the 944 Turbo. Its aerodynamic advantage enables it to reach 100mph in a stunning 14.9sec, more than three seconds ahead of the Quattro. And the Porsche goes on to reach a remarkable maximum speed of 157.9mph.”
Motor’s testers found the Quattro “more obviously the turbocharged car with vivid part-throttle response but quite a lot of lag. The Porsche’s throttle response is more akin to that of a normally aspirated engine”.
