Ben & Roxanne Miller (since 2013)
When new, hot-rodding a 2002 meant calling Alpina, which had effectively invented the BMW aftermarket.
Alpina offered cylinder heads, gearboxes, suspension components and everything else needed to transform an ordinary BMW into one with superlative, but still usable, performance.
The A4S was Alpina’s highest specification for a 2002 tii, with 190 hp at 7,400 rpm and 152 lb-ft at 5,500 rpm. The performance was a result of high-compression (11.0:1) Mahle pistons, a 320-degree camshaft, and modified connecting rods. The car also got Alpina’s lightweight flywheel, close-ratio five-speed gearbox, limited slip differential, wheels, seats, steering wheel, shift knob, front spoiler, emblems, upgraded brakes, suspension and exhaust. Thus modified, it dashed from 0 to 62 mph in just 7.4 seconds.
Alpina is believed to have built just 90 of its A4S engines. Adding the full suite of Alpina parts took the price of a 2002 tii to well over $12,000, quite a sum in the period.
Owner Ben Miller’s show-quality restoration pays tribute to Alpina’s quest for perfection. Even show cars need exercise, and both Miller and this 2002 are happiest when the A4S engine is able to rev past 7,000 rpm once in a while.
