- تحسينات كثيرة وتقنيات متطورة تم استخدامها وتوظيفها في السيارات المصنعة حديثا بهدف ضمان أعلى درجات السلامة والأمان لركاب السيارات الحديثة وللمشاة المحاذين لتلك المركبات .
وقد مرت صناعة السيارات عالميا بتطورات متسارعة ، وتم استخدام أفضل ما توصلت إليه الأبحاث والتجارب في هذا المجال ، فبالإضافة إلى أنظمة ABS لكوابح المركبات واستخدام الوسائد الهوائية لسلامة الركاب وتطوير كل من المرايا الكهربائية العاكسة والمقاعد ذاتية الضبط وأنظمة GPS وأنظمة الاتصالات اللاسلكية ، وغيرها من الأنظمة المتطورة ، إلا أن كل هذا التقدم لم يثن مصنعي المركبات من الاستمرار في إدخال أنظمة جديدة في السيارات المصنعة حديثا .
من أهم هذه الأنظمة ، نظام راداري متطور مثبت في مقدمة المركبة ، يعمل على بث واستقبال موجات خاصة ، تعطي السائق معلومات عن الحالة العامة للطريق ، وتجعل نظام الكمبيوتر في المركبة يرسم صورة واضحة للعوائق التي تقف في طريق السائق على شاشة إلكترونية مثبته في لوحة القيادة .
النظام الجديد قادر على اكتشاف المخاطر التي تحدق بسائق المركبة ، وبالتالي يعطيه النظام تحذيرا ضوئيا أو صوتيا فوريا ، يمكن السائق من استخدام الكوابح أو الانعطاف بمركبته وبالتالي تفادي تلك المخاطر التي قد تكون مدمرة للمركبة وللسائق.
نظام آخر تم تطويره مؤخرا ، يعمل على التعرف وقراءة الشواخص المرورية الموجودة على طرفي الشارع ، وإعلام السائق بمضمون تلك الشواخص من خلال الشاشة الرقمية المدمجة في لوحة قيادة السيارة ، أو من خلال صوت ناطق ينبعث داخل حجرة القيادة ، وبالتالي يتمكن السائق من التصرف المناسب في الوقت المناسب.

Smart (automobile)
The idea behind the "Smart car" was to create a vehicle easy to park and short enough to allow "nose-in" parking. Its length of 250 centimetres (98.4 in) would equal the width of a regular parking slot, allowing two or three Smarts to park in the space as one normal car.
The project, started by Swiss watch manufacturer Swatch, was nicknamed the "Swatchmobile". The name Smart is an acronym for Swatch Mercedes ART.[1] Intended to use innovative features (such as a hybrid engine) and be affordable for young people, the Smart had similar design objective to the Citroën 2CV of the 1940s.
Swatch CEO Nicolas Hayek sought an established car maker to produce his Swatch car. After General Motors reviewed and rejected the project as potentially unprofitable, Hayek found a partner in Volkswagen. Due to VW's own financial weakness at the time, plans never reached a final stage so Swatch teamed up with Daimler-Benz. The purpose-built factory complex Smartville in
An Australian dealer web site provides the following summary of the beginnings of the product:"How everything began: In 1993 Mercedes-Benz started a feasibility study on a subcompact car.
Together with the Swatch Group Ltd. they founded the Micro Compact Car AG in 1994. The Smart city-coupé celebrates its world première at the IAA in Frankfurt (
The final car design proved to be far from Hayek's expectations: its engine eco-technology was outside of Mercedes' goal. The joint venture experienced heavy losses and dispute then Swatch pulled out.
In 2005, DaimlerChrysler decided against purchasing a 50% share in the Dutch NedCar plant used to manufacture the Forfour supermini. DC also halted development on the Formore and decided to discontinue production of the Roadster.
In 2006, after dwindling sales, Smart GmbH was liquidated and its operations were absorbed within the Mercedes-Benz automobile group. It was later revealed that Smart GmbH lost nearly 4 billion euros from 2003 to 2006.
Models
Apart from the original short Smart Fortwo, a sporty Smart Roadster, a limited production of 2000 concept Smart Crosstown and a supermini Smart Forfour were also offered. These have now been discontinued. There were also plans to introduce a Brazilian-made cross-over based on the body of the ForFour and the AWD hardware of the Mercedes C-class with the name of Formore but industrialization of this was cancelled at the 11th hour (even as tooling was being installed in the assembly plant) due to unfavourable exchange rate swings and spending cutbacks driven by losses elsewhere within smart.

Safety
Smart vehicles use a very small front crumple zone. The new Smart Fortwo has been awarded 4 out of 5 stars in the Euro NCAP Adult Occupant Protection, 2 out of 4 stars in the Pedestrian protection test but it was not tested for Child Occupant Protection as it has no rear seats. The original Smart was awarded 3 out of 5 stars for Adult Occupant Protection. In American tests using a five star rating, Smart cars received a four star safety rating for the driver from a front impact, and a five star safety rating for the driver for a side impact. It also received "Good" ratings (top rating) for front and side crash protection in Insurance Institute for Highway Safety (IIHS) tests.
The main structure of the car is a stiff structure called a Tridion Safety Cell, which is designed to activate the crumple zones of a colliding vehicle. This design creates a very strong safety cell around the passengers.
Modification
Smart cars have been modified by Brabus of Germany, resulting in Brabus production models. Other companies modify the Smart to use motorcycle engines, such as the Suzuki Hayabusa 1352 cc inline four-cylinder. These cars are known as Smartuki. The most powerful models can accelerate from 0 to 60 mph (0 to 100 km/h) in less than 3.5 seconds.
Some companies and individuals upgrade the original engine to Brabus spec, but these have been taken even further by some with many aftermarket upgrade options available.

All Smart Cars imported through this arrangement will be registered with ZAP and the Department of Transportation to ensure that they meet government standards. The Smart Car gets 60 mpg and can reach speeds of 85 miles per hour, according to the ZAP Web site, and will range in price from $15,000 to $25,000 fully loaded.
The Smart Cars will be Americanized by G&K Automotive Conversions of Santa Ana, California, and distributed by Santa Rosa-based ZAP, a leader in fuel-efficient and eco-conscious cars.
