Speaking of the first generation 911 interior design, it is worth noting that even in 1964 Porsche was able to offer luxury. It featured luxurious leather seats and wooden paneling. In addition, the dashboard had a sound system. The layout of the dashboard is simple and based on a five-dial concept. The uniqueness of the Porsche 911 interior is the ignition key located on the left side of the steering wheel. This decision was made because Porsche engineers thought that by placing the ignition key socket on the left side, drivers would be able to save valuable time starting the car, since they could simultaneously engage first gear with their right hand while starting the engine with their left hand.

The first 911 models were equipped with a 6-cylinder engine. The cars also had an independent four-wheel suspension, which was a big advantage in tackling corners and distributing weight more evenly on the rear wheels, thus providing better traction.

In 1975, the new Porsche 911 930, also known as Porsche 911 Turbo, was introduced, and it was the fastest car produced in Germany at the time. Three essential changes were made to this model compared to its predecessor: the engine displacement was increased (up to 2687 cm), bumpers that absorb impact force were installed, and the K-Jetronic NVS Bosch fuel injection system was introduced.

The 911 was reviewed and redesigned to provide more power and comfort. The car's profile remained the same - a nearly vertical front windshield, a curved roof, and a sloping rear window that lined up with the engine hood. However, a new raised bumper with black plastic shock absorbers on the sides was well suited to this car and continued to be installed in other models.

The second-generation Porsche 911 had sport seats in the front and two smaller seats in the back. The five-dial instrument panel provided information about oil pressure, oil temperature, fuel level, a tachometer and a speedometer in the center, and an analog clock on the right. The ventilation controls were located at the same level as the steering wheel and stereo speaker.

Speaking of engines, the Porsche 911 930 had turbocharged, air-cooled six-cylinder engines. This car is very fast, so driving it is also a challenge. Due to the short wheelbase and rear engine, it tends to spin, and the turbocharger lags behind. Under certain conditions, if the accelerator pedal is pressed too hard, the heavy rear of the car sways from side to side like a see-saw, causing the car to spin. After several accidents and deaths caused by unfamiliar driving characteristics, it even earned the nickname "widowmaker." To this day, Porsche employees who drive 911 Turbo models for testing or work purposes must attend "Turbo training."

The third generation of Porsche was introduced in 1989. The 964 is the internal Porsche code that refers to the Porsche 911 Carrera 2 and 911 Carrera 4 models. The numbers "2" and "4" denote the number of driven wheels, as this 911 generation was the first to feature a four-wheel-drive system, as well as the first to feature an automatic "Tiptronic" gearbox.

The first 964 models to appear in 1989 were the Carrera 4 models with all-wheel drive, and in 1990 Porsche added the rear-wheel drive Carrera 2 variant to the lineup. Both variants were offered as coupes, Targas or cabriolets. In the Porsche 911 964 model, power steering and ABS brakes were first introduced, in addition to the automatic gearbox. Both of these elements were standard equipment.

Externally, the new Porsche 911 bumpers and fog lights were redesigned to improve the car's aerodynamics. To maintain stability on the road, a new electric spoiler was added to the rear of the car, which rises at speeds above 80 km/h. Inside the car, there were not many changes. Significant changes were made to the safety system, as the standard equipment of the 964 model included two airbags, for the driver and front passenger. This model also features a new automatic climate control system, providing better heating and cooling.

The third generation of the Porsche 911 models featured a six-cylinder engine, producing 260 horsepower and equipped with the latest systems that allowed for such a high power output at the time. The Carrera 4 all-wheel-drive system has self-locking differentials, which allows the car to accelerate from 0 to 100 km/h in 5.9 seconds. The new suspension system in the cars helped to develop higher speeds in corners.

In 1995, Porsche introduced the fourth generation of the 911, codenamed the 993, which was significantly updated and considered by some to be the last true 911 model. It was a blend of old and new school design, featuring sufficient comfort for daily use and excellent driving dynamics. Porsche claimed that each part of the car, including the engine, was created from scratch, with only 20% of parts carried over from the previous generation.

The 993 was a major improvement and departure from its predecessor. The base 911 model had the same round headlights with "bug eyes" and the distinctive Porsche 911 silhouette. However, the automatically-deploying rear spoiler was increased in size, and the wheel arches were significantly widened, along with more aggressive front and rear bumper designs. The interior remained largely unchanged.

The "VarioRam" system was introduced on this model, increasing the car's power output by 15%. This was also the first 911 model to feature a 6-speed manual gearbox and the last to use an air-cooled engine. Almost all variants of the model had a completely redesigned 3.6-liter six-cylinder engine.

Although technologically the Porsche 911 model took a big step forward, unfortunately, not everyone liked its design and it received a lot of criticism. Most of it was directed at the unusual shape of the front headlights, which no longer resembled the round "bug eyes" that had become a distinctive feature of the earlier models. The biggest difference was that the turn signals were no longer located on the bumper but at the bottom of the headlights. The completely new platform, which had a more curved front windshield and a lower body, also had a significant impact on the car's appearance. The profile, with a smooth body without any wheel arch enlargements, looked neat.

Inside the fifth-generation Porsche 911, there was a standard stereo speaker and air conditioning. The basic models do not have many luxury features, but they are included in the optional equipment list. The standard seats can be replaced with electrically adjustable leather seats. This is also the first Porsche 911 with a center console.

Under the hood, the biggest change was the switch to a water-cooled engine. The engine had a working volume of 3.4 liters and a power of 300 horsepower. In 2002, the engine's working volume was increased to 3.6 liters, and the power increased to 320 horsepower.

The sixth generation Porsche 911 was released in 2004, returning to performance and sacrificing some of the comfort offered by the 997 predecessor. The iconic "bug eyes" of the Porsche returned with this model, distinguishing it from the previous 996 model.

The 997 model is very similar in shape to the 996, and the most obvious difference is the front headlights. Experiments with the previous Porsche model did not justify the changes, so the classic "bug eyes" were brought back and the turn signals returned to the bumper. While almost a third of the parts in this model are new, technically they are similar. One of the engineering changes was a slight increase in power.

Inside, everything looks similar, with the 911's style maintained, but there are also a lot of differences. There is a new steering wheel, a new information and entertainment system, and new sport seats. With the installation of 6 airbags, the 997 generation improved the safety system of the Porsche 911. The "Porsche Communication Management" system was supplemented with a DVD-based navigation system and a 9-speaker stereo system, which was offered as additional equipment.

Under the hood, the Porsche 911 997 had a couple of engine options - some modifications had a 3.6 liter boxer six-cylinder engine producing 325 horsepower, while in the S versions a 3.8 liter engine producing 355 horsepower was installed, which is 30 horsepower more than the non-S versions.

In 2012, the seventh generation of the Porsche 911 was introduced. Although there are few noticeable exterior differences from the previous generation, this model is built on a new platform, is longer, has a longer wheelbase, and is wider. One of the main features that sets the 2012 Porsche 911 apart is its round front headlights and white DRL strips installed on the bumper. Three air intakes separated by the strips in the bumper enhance the sporty look of the car, but the overall shape of the car remains almost unchanged, which distinguishes the 911 from other cars. As with many other 911 models, a spoiler is installed at the rear of the car, which raises at high speeds to improve stability. The car has lost a considerable amount of weight due to the use of high-strength steel, aluminum, and some other composite materials, reducing the weight of the car by 45 kg.

The interior is more focused on luxury than on practicality. The new instrument panel still has a central tachometer, but on the left side of the analog gauge circle, a TFT screen is integrated.

The base version of the Porsche 911 991 uses 3.4 liters, 350 horsepower, and 3.8 liters with 400 horsepower engines. The latter can reach 100 km/h in 4.3 seconds. All 911 Carrera and 911 Turbo models can be equipped with the PDK 7-speed gearbox, which has manual and automatic modes. From 1 to 6 gears, it has a sporty transmission, and the highest speed is achieved in the 6th gear. The 7th gear helps to reduce fuel consumption while maintaining low engine speeds.

Compared to its predecessor, the Porsche 911 992 is 45mm wider and now features aluminum body parts. The 992 also has a new rear bumper with larger exhaust pipes than its predecessor. The front of the car is designed to modernize the appearance of the early 911. This generation features modern, electric pop-out door handles, a retractable rear spoiler (only for certain models), and LED headlights. There is also a full-width, extending strip of taillights.

In addition, the 8th generation 911 models have new safety features such as a lane departure warning system and a traffic sign recognition system. At night, the night vision assist uses a smart thermal imaging camera to detect people and animals and alert the driver.

The interior of these models has also undergone significant changes but has returned to the classic 911 model features. The dashboard has been redesigned to be flatter and reminiscent of the shape of the dashboards in older 911 models. Despite two 7-inch digital screens, an analog tachometer has been retained, also as a nod to the classic 911 models.

The engines of the new 992 models feature piezo injection and a revised intake system. At launch, the only available transmission was an 8-speed PDK dual-clutch gearbox, but now 7-speed and 6-speed manual gearboxes are also available. The more powerful 911 Carrera S and 911 Carrera 4S models are equipped with a six-cylinder turbocharged opposed engine producing 450 horsepower.
