Design
The body has been redesigned to be more curvaceous and aerodynamic. Although the drag coefficient remains the same, downforce has been greatly enhanced. A great deal of Ferrari heritage is found in the car: at the rear, the Enzo's tail lights and interior vents have been added. The car's name has been etched into the Testarossa-styled driver's side mirror. The large oval openings in the front bumper are reminiscent of Ferrari racing models from the 60s, specifically the 156 "sharknose" Formula One car and 250 TR61 Le Mans cars of Phil Hill.
Engine
The F430 features a 4.3L V8 petrol engine derived from a shared Ferrari/Maserati design. This new power plant is a significant departure for Ferrari: all previous Ferrari V8s were descendants of the Dino racing program of the 1950s. This fifty year development cycle came to an end with the entirely new 4.3L, the architecture of which is expected to replace the Dino-derived V12 in most other Ferrari cars. The engine's output specifications are: 490 PS (360 kW; 483 hp) at 8500 rpm and 465 N·m (343 lb·ft) of torque at 5250 rpm, 80% of which is available below 3500rpm. Despite a 20% increase in displacement, engine weight had grown by only 4 kg and engine dimensions have decreased, for easier packaging. The conrods, pistons and crankshaft are all entirely new, the four-valve cylinder head, valve heads and intake trumpets directly takes measurements from F1 engines, for better volumetric efficiency. The F430 has a top speed of 196 mph (315 km/h).[citation needed] Ferrari also claims the car sprints from 0 to 62 mph (100 km/h) in 4.0 seconds, 0.3 seconds quicker than the old model.Brakes
The brakes on the F430 were designed in close collaboration with Brembo.The result has been a new cast-iron alloy for the discs. The new alloy includes molybdenum which has better heat dissipation performance. Another option Ferrari is providing are Carbon fibre-reinforced Silicon Carbide (C/SiC) ceramic composite discs. Ceramics have much higher resistance to heat and brake fade than metals, the F430's brakes offer not only good performance but also a longer lifespan. Ferrari claims the brakes will not fade even after 300-360 laps at their test track.
Features
The F430 includes the E-Diff, a computer-controlled limited slip active differential which can vary the distribution of torque based on inputs such as steering angle and lateral acceleration.
Other notable features include the first application of Ferrari's manettino steering wheel-mounted control knod Drivers can select from five different settings which modify the vehicle's ESC system, "Skyhook" electronic suspension, transmission behavior, throttle response, and E-Diff. The feature is similar to Land Rover's "Terrain Response" system.
The Ferrari F430 was also released with exclusive Goodyear Eagle F1 GSD3 EMT tires, which have a striking V-shaped tread design, run-flat capability, and OneTRED technology.
In the US, the company requested an exemption from the airbag design requirements, which was eventually granted, allowing the car to continue to be sold in the US.2. FERRARI CALAFORNIA

The Mercedes-Benz E-Class is a range of executive-size cars manufactured by Mercedes-Benz in various engine and body configurations. The E initially stood for Einspritzmotor, (German for fuel injection engine); a new feature in volume production vehicles at the time that the E-Class first appeared, with the E as a suffix to the engine nomenclature (e.g. 230E) in the 1950s. It was not until the launch of the facelifted W124 that the E was used as a prefix (i.e., E220) and the model referred to officially as the E-Class (or E-Klasse). At this time all Mercedes cars used fuel injection and the company felt it was not necessary to add this as a distinguishing feature. Due to the E-Class's size and durability, the cars also frequently serve as taxis in European countries. Older models like the W123 and W124 are used in Malaysia as inter-state taxis, and the W211 is used in Singapore as a taxi. Mercedes-Benz also offers special-purpose vehicles (e.g., police or ambulance modifications) from the factory. 4. HUMMER H3
