New Subaru Impreza STI Cosworth CS400 is the expected result of a car co-operation in recent times. Cosworth developed the first real road car since 1996, the latest limited edition Impreza offers fans the thrill of the car performance, combined with the exclusive right to life - the production is limited to 75 cars.
Listening-Cosworth, a turbo car is one of the most sedans acceleration. The familiar 2.5-liter engine turbocharged 'boxer' is converted to produce the force by 33 percent more than Cosworth relies heavily on extensive experience in Formula 1. The engine that drives all four wheels via a six-speed manual gearbox, and boasts an impressive 400 hp and the new model reaches 62 km / h in just 3.7 seconds, going on to cover the quarter mile in 12, 75 seconds at a terminal velocity of 107 km / h. The maximum speed is limited to 155 mph.
Marketed only in the right hand drive form in the United Kingdom, the Subaru Impreza STI Cosworth CS400 is available in a choice of three exterior colors (Spark Silver, dark gray, and the San Remo Red), and is priced at £ 49 995 on -the-road.
The engine delivers 33 percent power hike
At the heart of the new Subaru Impreza Cosworth is a heavily revised version of the famous mark horizontally, on the contrary, all-aluminum boxer engine. "Flat-four 'power is disconnected from the machine, hand finished, and the number of internal components are replaced during good and associated articles, as defined by Cosworth.
As with all Impreza engine "Boxer", the apartment STI Cosworth with twin overhead camshafts per bank (DOHC) and Active Valve Control System (AVCS) variable valve timing of the supply and improve low-speed pulling power.
Focus on an update of the Cosworth engine was to keep the maintenance improvements of a simple, efficient and closer to the original design of equipment to ensure reliability and ease of a normal Subaru dealerships.
Internal improvements are high-performance pistons, which are manufactured using the same methods are used to create Cosworth Formula 1 pistons. Special features to reduce the accumulation of carbon to minimize friction and reduce weight.
Forged connecting rods are made of high strength 4340 (EN24) steel and special bearings Cosworth engine offers a unique combination of design, metallurgy and engineering. Heavy duty cylinder studs high performance head gaskets multi-layer and a high pressure pump is also equipped with oil.
The overall result is a huge increase in torque, the highest RPM range, and significantly improved in-gear acceleration. This makes the Impreza more adaptable and daily traffic, but also much sharper tool path.
New turbocharger and "breathe" exhaust systems
A new system design has a new Cosworth supercharger compressor and relief valve actuator to provide increased boost pressure and deliver more power.
A single exhaust system was developed to allow the engine to "breathe" more easily and release their full potential. Increased capacity of collectors and downpipes tubular diameter in order to accelerate the elimination of hot gases. The first catalyst is a non-restrictive design and exhausts to the exhaust note of a single tone.
After the update in-depth performance Cosworth, with a new computer map, the boxer engine in the CS400 produces 33 percent more horsepower (400 hp at 5,750 rpm vs. 300 hp at 6000 rpm for standard Subaru Impreza WRX STI) and 542 Nm of torque, while remaining within the limits of torque to the design capacity of the original transmission Impreza.
Manual transmission and all wheel drive
To handle the increase in power-tuned Cosworth engine, gearbox Subaru Impreza STI six-speed manual, which is synchronized carbon applied to the top three ratios and a short-range clutch to accelerate change.
It also updates the oil bath controlled the pressure plate, bearings and disc. The gearbox and final drive ratios are the same.
The Subaru Impreza Cosworth full-time four-wheel-drive front wheel drive and rear limited slip differentials, features a 50/50 front to rear torque distribution, as the default, however, the distribution of electronically torque is varied according to changing conditions. The multi-mode driver control center differential with viscous coupling senses which axle has the best grip and varies the split ratio in milliseconds to distribute torque accordingly, thus maximizing traction and minimize slippage.
Improve management of the Cosworth Subaru Impreza, steering feel and driver feedback - without compromising ride comfort - it was a priority for the development team.
Subaru have available the original suspension and main components, Cosworth and a team of engineers worked with Bilstein Eibach Chassis and technicians to design a tour package / handling / director, who was perfectly suited to the improved performance of the new model.
Eibach springs and Bilstein Special new inserts with unique features of depreciation, were made to the specifications of Cosworth. The ride height has been lowered 10 mm front.
The advantages of this reduction is twofold. First, there is a big improvement in ride quality in general, the Impreza's easy to live with day to day. Secondly, the limit behavior in more focused and serene. Improved damping means less pitch and roll when cornering at the corners, which means that drivers who wish may return to the office early and get the most out of the car Symmetrical All-Wheel-Drive.
Update "racing" brake to improve braking power
To match the new Subaru Impreza Cosworth super pace, commissioned Cosworth to develop AP Racing front brakes more powerful. Larger diameter (355 mm) vented front discs have been adopted, with kettle-style racing with six-piston calipers in the personal operating larger brake pads.
The performance difference is immediately apparent. Harder pads to minimize the loss of color, which means that drivers can rely on AP plugs actually slow down time and time again.
The standard Subaru Impreza WRX STI rear brake discs, brake balance and all of the ABS home has been preserved.
"Stand-out" looks, plus new style wheels
The excellent performance of the Cosworth Subaru Impreza is reflected in its "stand-out appearance and standard xenon headlights. The lowered ride height and wider track gives the car a whole new attitude that is reinforced by a new front bumper, new fog lights, upper and lower mesh grilles and a new rear spoiler.
Discreet Cosworth badge conducted in the lower front grille, front seats, calipers and pads. The individually numbered plates are mounted on the engine and thresholds. Each of the Subaru Impreza STI Cosworth CS400 with a numbered certificate of authenticity.
Despite alloy wheels the new model are very similar in size to the regular Impreza WRX STI model - 18 x 8.5 inches - which are lighter and stronger. Called "Pro Race" and finished last in the range of Team Dynamics wheels anthracite were selected to be compatible with the Subaru design studies of five years. These wheels have an offset of 43 mm (standard STD scroll wheel is 55 mm) and extend the track by 12 mm - improving handling and filling the wheel arches of the car more efficiently for a position more aggressive.
The new wheels are equipped with high performance, low-profile Michelin tires SP3 chosen for their traction on dry and wet, durability and low noise. Tire size is 245/40 R18 and sculpture is directional.
Interior modifications and equipment prices generous
Inside, new front Recaro sport seats, rear seats and steering wheel are re-branded black leather-trimmed Cosworth. Also distinguish the CS400 is the piano black center console and accent finishes, and installation of tinted glass.
