Origin
editDeveloped inTurin,Italy, the Compact platform was designed to adapt to future cars of both the Fiat andChryslergroup. Developed a new high-performance platform that uses only a front central part of the floor from the old C-platform. The frame composition is 84% high-strength steel (as opposed to the old C-platform, 65% of which was high-strength steel) and 4% aluminum, and magnesium. The frontsuspensionusesMacPhersonEvo struts with aluminum uprights and is 4 kilograms (8.8 lb) lighter than the previous design with steel uprights (as used in the Fiat Bravo). The rear suspension uses an independent multi-link suspension and each of them consists of two lateral links with an aluminum longitudinal arm that mounts the hub and spring.[3]Using aluminium rather than steel, which has a higher density, enabled a total combined weight-savings in the suspension bits of 14 kilograms. The framework for the rear seats and the magnesium alloy cross member reduced weight by 35% in comparison to earlier cars.[4]
The platform offers a compact transverse engine at the front with either front or four-wheel drive. The total platform weight of the standard version (on the compact models) is 174 kilograms (384 lb).
Long wheelbase version (Compact Wide)
editThe long wheelbase version is calledCompact Wideand was used for US-built models of Chryslersedanslike theDodge DartandChrysler 200.The CUSW products first appeared in late 2011.[5]The interchangeable modules make the basic platform suitable for vehicles of differing lengths up to 4.92 metres (16.1 ft). It was designed with additional features for a compact platform that could adapt to sports cars likeAlfa Romeo.
The engine range, combined with the platform, consists of the compact four-cylinder petrol 1.4Fire,1.4Multiair,1.75 TBiturbocharged,the 2.0 or 2.4Chrysler GEMAengine, the 3.2 or the 3.6Chrysler PentastarV6 engine, and the 1.6, 2.0 and 2.2Multijetturbodiesel engines. Fiat and Chrysler planned to build about 1 million vehicles a year by 2014 based on this platform. Eight upcoming Chrysler Group vehicles are planned to be built on Fiat's Compact Wide platform, including the replacement for the Jeep Liberty.[6]
