With the exciting release of the 2022 Toyota Tundra Hybrid, the automotive industry will see the rebirth of the parallel hybrid powertrain system. This is done by sandwiching a 3-phase motor/generator (known as IMG, for single motor generator, in Toyota terminology) between the internal combustion engine and a traditional automatic transmission. Like other hybrid platforms, the motor generator is used during low-speed driving and to aid the engine during high-load driving in situations such as towing. The parallel hybrid system is a departure from the series-parallel hybrid that Toyota has become known for. To understand this change, it is beneficial to understand the differences between the three core types of hybrids currently on the road today. |
