In June 2014, [4] Volvo Trucks presented a new dual-clutch version of the I-Shift, known as SPO2812, with overdrive and a maximum torque of 2800 N·m. [5] The dual-clutch version is only available for trucks up to 540 hp. The I-Shift Dual Clutch has two input shafts which are alternatively connected to the engine through two clutches.
In 2001 Volvo introduced the second generation of the FH and FM series with the cab and driveline given a major makeover. [11] with an investment cost of €600 million [12] Major changes included a redesign of the cab to improve aerodynamics, the new automatic gearchange transmission, I shift, new electronics system and engine improvements.
Geartronic is Volvo Cars' name for its manumatic automatic transmission, similar to Porsche's Tiptronic. It is available in 4-, 5-, 6-, and 8-speed models, and is controlled by a microprocessor . The microprocessor automatically shifts to the next gear if a user in manual mode red lines the engine.
When it is switched on, an automatic transmission can shift into overdrive mode after a certain speed is reached (usually 70+ km/h [40-45 mph or more] depending on the load). When it is off, the automatic transmission shifting is limited to the lower gears. Overdrive should usually be selected when the average speed is above 70 km/h (40-45 mph).
E.g. in a truck with a Caterpillar C15 engine, it is achieved by going all the way up to 1950RPM, then shifting to a gear that will put the engine at 1500RPM. In contrast, using progressive shifting, i.e. maintaining maximum torque , the overall acceleration is slower but there is increased fuel efficiency and lower wear of the engine due to ...
The Swedish brand is limiting the top speed on all its cars to 112MPH starting with the 2021 model year. Safety technology and city infrastructure isn't enough to prevent injuries at high speeds ...
Powershifting, also known as full-throttle shifting or flat-shifting, is a method of gear shifting used with manual transmissions to reduce the time where the driving wheels are not powered. Unlike during a normal gear change, in a powershift the driver does not let off the accelerator.
