All about Great Wall

On April 26, the founder of Astana Motors, and the founder of Great Wall Motor, Wei Jianjun, held negotiations. Both companies will strengthen their cooperation. the plans include the production of the TANK 300 model at Astana Motors’ new multi-brand plant.

Astana Motors also announced the renewal of the model line of brands included in Great Wall Motor in Kazakhstan. In particular, the Tank 700, the new flagship of the brand, will go on sale this year.

Astana Motors is building a plant in the Almaty industrial zone which will produce cars for the Changan, Haval, and Chery brands.

Based on Astana Motors press release 

On April 25, at the Auto China 2024 in Beijing, Great Wall Motor (GWM) unveiled star models such as the next-generation Haval H6, the next-generation Haval H9, and the 2024 Haval Raptor.

The next-generation Haval H6 employs the “Galaxy Aesthetics” design language. It is available with powertrains consisting of a 1.5T engine and a 7-speed dual-clutch transmission (DCT) or a 2.0T engine and a 9-speed DCT. Specifically, the 2.0T edition is equipped with a 4N20A engine and a GWM in-house developed transverse 9-speed DCT, delivering a maximum power of 175kW and a peak torque of 385Nm. Configuration-wise, the vehicle comes with the Coffee OS 2.0 intelligent cockpit system and the Coffee Pilot intelligent driving system.

Positioned as an “intelligent all-terrain family SUV”, the next-generation Haval H9 draws exterior design inspiration from Chinese philosophy to present an open and majestic look. The interior follows a simple yet powerful style and contains a 14.6-inch center console display.

From a Haval press release

Eaton announced it has been chosen to supply an electromechanical actuation system (EMAS) that can deliver an early intake valve closing (EIVC) to Great Wall for use in a line of hybrid-electric vehicles (HV). 

The Eaton EMAS is a discrete valvetrain-based technology that allows manufacturers to select the intake lift that best fits the engine map. At low to medium engine speed and torque, the system delivers the EIVC function, reducing the air trapped in the cylinder and the pumping losses, which increases overall engine efficiency. When the engine requires maximum performance, the system can switch to the longer valve event, delivering the highest output possible. 

Leveraging a system that can be easily integrated into the valvetrain and the cylinder head space and controlled by a simple electric actuator, the EMAS creates a balance between fuel economy and performance

Eaton’s innovative new system differs from traditional variable valve actuation (VVA) solutions in that it includes switchable rockers, a mechanical actuation shaft controlling the switching of the rockers, and an electric actuator driving the actuation system on demand. 

The switchable rocker arm is composed of stamped and cold-formed parts, to enhance manufacturability without impacting performance. (Eaton press release on April 23, 2024)
