Volkswagen has officially launched a new full hybrid system for its popular models, the Golf and T-Roc. This innovative hybrid drive enhances both performance and efficiency for these vehicles.
Overview of the Hybrid Drive System
The new hybrid drive system integrates several advanced components. At its core is a hybrid module paired with a turbocharged petrol engine, specifically the 1.5 TSI evo2. This module also contains:
- An electric motor for driving power
- A secondary electric motor functioning as a generator
- Power electronics for efficient control
- A differential and one-speed gearbox
- An electronically controlled multiplate clutch
- An electric A/C compressor and brake servo
The lithium-ion battery designed for this hybrid system has a gross capacity of 1.6 kWh. This battery is strategically positioned in the rear vehicle floor, maximizing space within the Golf and T-Roc.
Operating Modes for Optimal Efficiency
Volkswagen’s hybrid drive system operates using three distinct modes, automatically adapting based on driving conditions:
- Propulsion Mode: The vehicle runs solely on electric power, offering a quiet driving experience at low speeds.
- Serial Drive: The electric motor operates alongside a decoupled TSI, generating energy through a generator to extend electric range.
- Parallel Drive: The petrol engine becomes the primary power source at higher speeds, with the electric motor aiding acceleration.
Driver-Selectable Driving Profiles
The Golf Hybrid and T-Roc Hybrid feature three selectable driving profiles: Eco, Comfort, and Sport. Each profile adjusts the vehicle’s performance and efficiency:
- Eco: Limits system output to 70% and deactivates boost function to conserve energy.
- Comfort: No output limitation, allowing for boosted performance.
- Sport: Prioritizes sporty dynamics by shifting to serial mode earlier for immediate power delivery.
This new hybrid technology from Volkswagen redefines efficiency while maintaining the performance standards that drivers expect. The Golf and T-Roc can now offer a smooth and quiet experience, particularly beneficial in urban settings.
