BMW 330i E90

I decided to convert "just an ordinary car" that you can see a dozen times a day on the streets of any more or less large city.

The BMW 330i accelerates from 0 to 100 km/h in 6.3 seconds. Top speed is limited to 250 km/h; fuel consumption in the EU cycle is
8.7 l/100 km.

Production period: from 2005 to 2008, followed by a facelift in 2009.

The body kits will be set to the interior trim variants.

The very latest kit turns the car into a BMW 320si WTCC.

BMW 320si WTCC

It was developed by BMW Motorsport based on the base 3 Series model. To date, the car has countless victories in the World Touring Car Championship, as well as in numerous national championships. At the moment, more than 60 cars have been delivered to BMW Motorsport customers.

The BMW 320si WTCC body with a roll cage is produced at the BMW plant in Regensburg, along with bodies for the BMW 1 and 3 Series. Significant changes were made to the transmission design. So that the driver doesn't have to press the clutch every time when downshifting, a special electronic system was introduced. A sensor is integrated into the gear lever. This sensor sends a signal to the engine control unit when the pilot places a hand on the lever. This impulse reduces the traction force in the engine control unit, allowing the driver to shift down smoothly and quickly without using the clutch.

The engineers are seriously interested in optimally changing the axes and suspension geometry. They plan to include a special camber parameter in the axle design so that it can be adjusted independently of other parameters, such as the roll center and directional stability. All this will allow semi-professional teams to set up the car faster. Track width and camber were also increased.

High-strength materials are used in the brake design of the BMW 320si WTCC. At the front, steel perforated brake discs measuring 332 mm by 32 mm and 4-piston fixed calipers are installed. At the rear, ventilated brake discs measuring 291 mm by 18 mm and 2-piston fixed calipers are installed. The rack-and-pinion steering of the BMW 320si WTCC is assisted by an electro-hydraulic system borrowed from the production model. The only difference between the racing steering and the production one is that the steering gear ratio is more precise.

BMW Motorsport relies on its expertise and produces the main components for its high-performance engines at the BMW plant in Landshut, where the main engine components are also produced. A 2-liter, four-cylinder engine from the BMW 320si (127 kW/173 hp) is currently being produced, and 45 units are being made for racing. The BMW 320si WTCC uses a 5-speed dog-type gearbox and a clutchless transmission.

Addon

On a large portal dedicated to 3d car modeling, I came across a model available for download marked "author unknown". The quality of the model suited me, and the thought flashed through my head, "and why not?"

During preparation it became clear - the model is from GTA San Andreas, but you won't find the author, because for GTA cars are churned out by any self-respecting representative of the schoolkids...

So, wait soon!
