The doors of the BMW 3 Series are made of steel, not aluminum. Here are some details: 1. The body of the BMW 3 Series is not made of aluminum alloy but steel plate. 2. The domestic long-wheelbase version is 40kg heavier than the standard-wheelbase version, so the domestic 3 Series does not use aluminum alloy body panels. Below is some information about the new generation BMW 3 Series: (1) Built on the CLAR platform, the long-wheelbase version has been further extended in size, with dimensions of 4829/1827/1463mm and a wheelbase of 2961mm. Compared to the current model, the wheelbase is extended by 41mm, and the length is increased by 69mm, with slight adjustments in width and height to meet the 'big' demand of the Chinese market. (2) The interior is enhanced with a sense of luxury, and it comes standard with 18 features, including a 12.3-inch full LCD dashboard and a 10.25-inch central control display. (3) The new 3 Series also supports wireless Apple Carplay, a parking assistant system, ambient lighting, and a three-zone independent air conditioning system as standard.

What causes shaking when idling in first gear?

Here are the specific reasons for shaking when idling in first gear: 1. Driving habits: Shaking during first gear starts is likely caused by the driver's habits. 2. Excessive wear of the clutch pressure plate: Manual transmissions primarily transmit power through the clutch, and the clutch pressure plate is mainly responsible for transferring kinetic energy. The clutch pressure plate has a lifespan, and prolonged semi-engagement or the engine operating under excessive load can accelerate wear. When the pressure plate wears to a certain extent, power engagement becomes less smooth, causing the car to shake and the engine speed to become unstable. 3. Wear of the flywheel and clutch disc: Irregular wear of the flywheel and clutch disc, key components of the clutch, can lead to misalignment. During engagement, the clutch disc cannot smoothly engage.

Will the Model S be domestically produced?

Model S is a vehicle model produced by Tesla. Tesla Motors was founded in 2003. Although its electric vehicles are energy-efficient and environmentally friendly, the company struggled to find its market and remained unprofitable for the past decade. However, in the first quarter of 2013, Tesla finally turned a profit, largely due to the launch of the Model S on June 22, 2012. It is expected that the Model S will not be domestically produced in the short to medium term. Tesla's current focus at its domestic factory is on increasing production volume. Therefore, introducing the Model S, a niche model, for domestic production would impact the capacity and supply chain localization of other mass-produced models.
