Review: Audi 8P.I S3 (2007-08)

Overview

Released in June 2007, the Audi 8P Series I (8P.I) S3 was a small, three-door hatchback. Manufactured in Ingolstadt, Germany, the Audi 8P S3 was powered by a 2.0-litre turbocharged four-cylinder engine that was mated to a six-speed manual transmission.

2.0 TFSI engine

Compared to the 2.0 TFSI engine in the Volkswagen Mk.5 Golf GTi (engine codes: AXX, BWA and BPY ), changes for the Audi 8P S3’s BZC and CDLC engines included:

A reinforced cylinder block at the main-bearing pedestals and main-bearing caps;
A new high-flow cylinder head made from aluminium-silicon alloy for high temperature resistance;
Long-duration camshafts and revised exhaust camshaft timing;
Uprated piston (wrist) pins, piston rings and connecting rods with new bearings;
Annular valve seats;
A larger BorgWarner K04 turbocharger which provided peak boost pressure of 1.2 bar (up from 0.9 bar);
A larger intercooler and radiator cores; and,
A lower compression ratio of 9.8:1 (compared to 10.5:1).

The Audi 8P S3 could accelerate from rest to 100 km/h in 5.7 seconds.

Dimensions, suspension and steering

The 8P S3 was based on Volkswagen’s PQ35 platform which also underpinned the Audi 8P A3 and Mk.5 Golf . Compared to the Audi 8L S3 , the 8P S3 was 44 mm longer (at 4203 mm), 2 mm wider (1765 mm), 6 mm taller (1421 mm) and had a 58 mm longer wheelbase (2577 mm). The S3 had MacPherson strut front suspension with unequal length wishbones, four-link rear suspension and an electromechanical steering system.

Compared to the Audi 8P A3 , the S3 was distinguished by its 25 mm lower ride height and stiffer suspension tune, while visual cues included its chromed single-frame grille, front spoiler with large air inlets, restyled side sills and a rear diffuser.

quattro

The Audi S3 was fitted with a second generation Haldex all-wheel drive system which consisted of Haldex electronically-controlled multi-plate clutch, an open rear differential and an open front differential with an electronic differential lock. In normal conditions, 90 per cent of the engine’s torque was directed to the front axle, but up to 50 per cent of the engine’s torque could be directed to the rear wheels in the event that traction was lost.

Safety equipment

Standard safety equipment for the Audi 8P S3 included dual front airbags, front side airbags, full-length curtain airbags (i.e. for front and rear occupants), ABS, electronic brake force distribution, brake assist, electronic stability control, traction control, active front seat head restraints and front seatbelts with pretensioners and load limiters.
