Ford Mustang SVT Cobra

The Ford Mustang SVT Cobra was a pony car built by Ford Motor Company through the Special Vehicle Team division. It is a high-performance version of the Mustang built by Ford, sitting in the model range above the Mustang GT model. On three occasions, Ford also produced an even higher performance Cobra R variant. Although the Shelby GT500 Mustang is built in part by SVT, and bears the Cobra badge, it is not considered an SVT Cobra, as it is licensed by Shelby and doesn't have Cobra anywhere in its description or name.

The 1993 Ford Mustang SVT Cobra was launched during the 1992 Chicago Auto Show. It was the premier vehicle of Ford's newly established SVT division, designed to showcase SVT's four hallmarks of Performance, Substance, Exclusivity and Value.[1] The exterior of the 1993 SVT Cobra does not represent a radical departure from the year's GT model: However, there are subtle differences, as explained below.

The true redesign and upgrade occurred beneath the bodywork: The powertrain was driven by a 302 CID V8 (5.0L) motor, producing 235 hp (175 kW) and 280 ft·lbs (380 N·m) of torque. According to Road & Track, this could send a Cobra through the 1/4 mile in 14.5 seconds at a top speed of 98 mph (158 km/h). Acceleration from zero to 60 mph (97 km/h) took 5.9 seconds.[2] The drivetrain received an upgraded transmission, rear disc brakes, and for the first time on a factory Mustang, 17" unidirectional wheels. The suspension was not neglected, either: Cobra models received a softer, more compliant ride compared to the GT model. This was accomplished with model-specific springs and sway bars.

Note: Ford part numbers are listed below. In many cases Ford has two separate numbers for each part, the Ford production number (the fourth character is a Z), and an engineering number. The engineering number is usually what is stamped/cast on the part itself (the fourth character is E for engine parts, F for electronics, and C for chassis).

Engine
The 1993 SVT Cobra's short block (cylinder block, crankshaft, rods, and pistons) was carried over from the GT model. To this, Ford SVT engineers added the following performance items:[3]

Cylinder Heads: GT-40 "High Flow" Cast Iron heads were installed. They were milled for 62.5 cc combustion chambers. Valves measure 1.84" (46.7 mm) intake, and 1.54" (39.1 mm) exhaust. The valves are actuated by Cobra-specific 1.7 ratio roller rockers, constructed of aluminum and produced for Ford by Crane Cams. Part Numbers: F3ZZ-6049-B (head), F3ZZ-6507-A (intake valve), F3ZZ-6505-A (exhaust valve), F3ZE-6529-AB (rockers).
Intake Manifold: The Cobra upper manifold was unique to the 1993 Cobra and had a 2.75" (70.0mm) diameter round throttle body opening, diverting air into (8) round staggered ports, each 1.64" (41.7 mm) diameter. The lower manifold was identical to the GT-40 manifold used by Ford Racing; it redirects airflow to a rectangular port configuration as needed by the cylinder heads. Part Numbers: F3ZZ-9424-C (upper manifold),F3ZZ-9424-D (lower).
Camshaft: The cam is of the hydraulic roller type (same as the GT). However, the Cobra cam has unique specifications of 0.479"/0.479" (12.2 mm/12.2 mm) intake/exhaust lift, (209°/209°) duration at 0.050" (1.27 mm), and a lobe separation of 118.3°, Part Number: F3ZE-6250-CA.
Air/Fuel Delivery: The increased airflow and fuel consumption of the Cobra required these upgraded components: Larger (compared to the GT) 24 lb/hr fuel injectors, 2.75" (70.0 mm) MAF meter, 2.56" (65.0 mm) throttle body, and matching EGR plate handle the increased breathing of the motor.

Peugeot RC

The RC concept was designed at the Peugeot Style Centre. Intended as a true enthusiasts car, the real innovation lay in the fact that the car was designed as an "affordable" sports car. The Peugeot RC was the concept car that paved the way for the 2008 Peugeot RC HYmotion4 concept. Peugeot used the 2002 RC concept to compare performance and economy differences between comparable petrol and diesel engines. As an affordable sports car the RC had to deliver not only in terms of price, but there was the engine, the size and running costs, as well as driver comforts to consider. A wide panoramic windscreen and the cab forward seating helps the driver see all around the car and compensates for the effect caused by the length of the car. In the Petrol vs. Diesel experiment, Peugeot aimed to prove that an HDi engine could match the performance levels achieved from a petrol engine. And to demonstrate that it was not unreasonable to put an HDi engine in a sports car. The 2 resulti...

KTM X-Bow Superlight

The extensive use of bare carbon fibre has kept the weight to a minimum The KTM X-Bow Superlight is one of the variants of the KTM X-Bow model range. As the name suggests the Superlight is the lightest model in the range - but not by much, the base model KTM X-Bow is just 5 kg (11 lbs) heavier. Although the Superlight is a full 40 kg (88 lbs) lighter than the GT4 version. The weight reductions to the KTM X-Bow Superlight have been made possible through the extensive use of carbon fibre. The monocoque structure with integrated crash protection is composed entirely of carbon fibre and left unpainted to show of the carbon fibre weave. The few body panels which are fitted to the X-Bow Superlight are also formed from carbon fibre. Additional weight savings were also achieved through the use of unique light-alloy wheels finished in a dark lacquer. Powering the KTM X-Bow Superlight is the same Audi-sourced 2.0 litre turbocharged engine found in all the X-Bow models. This engine puts out 24...

Maserati Ghibli vs BMW 6 Series : Which Will You Buy?

When considering vehicles like Maserati Ghibli and the BWM 6 Series Gran Coupe, both reflect an effort toward blending dignified luxury with exhilarating performance. Though beholding vehicles of this caliber is always an exercise most fruitfully left to the natural eye, the image above serves as a simple example of each sedan’s inherent dignity. In lieu of experiencing each vehicle’s performance profile from behind the wheel, the table provided similarly works to demonstrate what both Ghibli and BMW’s 6 series have been engineered to accomplish. Comparing the Maserati Ghibli vs. BMW 6 Series in this regard yields a number of important emphases. Local clients will notice that both vehicles develop their identity around six-cylinder engines with a pair of strategic turbochargers. Yet regardless of identical displacement and analogous induction technology, Maserati serves its Ghibli clients with significantly greater quantities of horsepower and torque. In addition to t...
