Powertrain & Engine Architecture
At the heart of the 997 Carrera 4S 3.8 lies the M97.01 engine, a 3.8-liter naturally aspirated flat-six (boxer) engine. This engine represented a significant upgrade over the 3.6-liter units found in earlier 997 Carrera models. The M97.01 featured an increased bore and stroke, along with revised cylinder heads and intake systems, contributing to its higher output. It utilized a multi-port fuel injection system, delivering fuel directly into the intake ports. The engine’s valvetrain employed dual overhead camshafts (DOHC) with four valves per cylinder, optimizing airflow for improved performance. The engine produced 355 horsepower at 6,600 rpm and 400 Nm (295 lb-ft) of torque at 4,600 rpm. The 6-speed manual transmission was standard, providing precise gear changes and a direct connection to the engine.
Driving Characteristics
The Carrera 4S 3.8 offered a compelling driving experience. The 3.8-liter engine provided ample power throughout the rev range, delivering strong acceleration and a responsive feel. The all-wheel-drive system enhanced traction, particularly in adverse weather conditions, making the car more predictable and confidence-inspiring. While not as brutally fast as the Turbo models, the Carrera 4S 3.8 offered a more balanced and accessible performance profile. The manual transmission’s gear ratios were well-matched to the engine’s power curve, allowing for spirited driving on both the road and the track. Compared to the base Carrera, the 4S provided a noticeably more engaging and capable driving experience, while remaining relatively easy to drive.
Equipment & Trim Levels
The Carrera 4S 3.8 came standard with a generous array of features, including leather upholstery, automatic climate control, a Bose sound system, and bi-xenon headlights. Optional extras were plentiful, allowing buyers to personalize their vehicles. Popular options included sport seats, a sunroof, navigation system, and Porsche Active Suspension Management (PASM), which allowed drivers to adjust the firmness of the suspension. Interior trim options included various leather colors and materials, as well as carbon fiber accents. The Carrera 4S 3.8 was positioned as a premium offering within the 997 range, and its standard equipment reflected this.
Chassis & Braking
The 997 Carrera 4S 3.8 featured a robust chassis designed for both performance and comfort. The suspension utilized independent McPherson struts at the front and a multi-link setup at the rear. The all-wheel-drive system distributed power to all four wheels, enhancing traction and stability. Braking duties were handled by ventilated discs at all four corners, providing ample stopping power. The Carrera 4S 3.8 also featured an advanced anti-lock braking system (ABS) and electronic stability control (ESC) to further enhance safety. The car’s weight distribution was carefully optimized to improve handling and balance.
