Auto Expo 2012: DC Avanti supercar makes its debut

Article by Christian A., on January 5, 2012

The first Indian designed supercar named the DC Avanti has just been introduced at the Delhi motor show. Initially, a mid-mounted, Ford-sourced, 2.0-litre four-cylinder turbocharged petrol engine will be available. This could deliver 261bhp. The company will release a V6 version, which produces 394bhp, at a later date. These two engines are linked to a six-speed dual clutch transmission.

The Avanti weighs 1560kg and it uses aluminum extensively. The owners assert that the base model could accelerate to 62mph in less than seven seconds.

DC Design aims to produce 200 cars annually for now but it has set a goal to produce 2000 cars a year longer term. This car will be offered in the various dedicated Avanti showrooms throughout India.

A rival for the Ferrari 458 Italia

As proof that the new Ferrari 458 Italia is indeed totally different from the previous models, all that needs to be done is to look at the Pininfarina design. Through the use of the aerodynamic and compact form, it helps highlight the concepts that originally inspired the project which is that of simplicity, lightness, and efficiency. Like with every model that Ferrari has released, the style of the new model is strongly influenced by the need to have aerodynamic efficiency.

A good example of this is the downforce of 140 kg created by the model at 200 km/h. The front section only has a single opening for its front grille and even that of the side air intakes. There are also aerodynamic profiles and sections that have been designed in order to channel the air not only to the coolant radiators but also the new flat underbody.

This new model’s nose has small aeroelastic winglets which help create downforce. Once the speed increases, the winglets deform in order to lower the section of the vehicle’s radiator inlets and thus cut drag. It is worth noting that during the model’s design phase, the engineers put focus on lowering the weight as part of performance considerations. The result is that the Ferrari 458 Italia has a dry weight measuring 1,380 kg. This also results in a power-to-weight ratio at 2.42 kg/CV. Weight distribution meanwhile has been optimized with 58% of it over the axle in the rear.

The work done by the engineers can be summarized in two figures that when taken together, summing up perfectly the exceptional performance of this new model. Maximum speed is at least 325 km/h, with acceleration from 0 to 100 km/h possible in 3.4 seconds. The Ferrari 458 Italia has a new chassis, which like the previous versions, is composed of aluminum. However the engineers at Maranello incorporated as well different types of advanced alloys in addition to bonding and manufacturing methods coming from the aerospace industry.

The new Ferrari 458 Italia is fitted with the 4,499-cc V8 engine. While this is not the first direct injection engine from Ferrari, it is the first such engine to be mounted mid-rear. The engine has a very low piston compression height that is present in standard racing engines. This helps the engine get a 12.5:1 compression ratio. Being equipped with the typical flat-plane crankshaft, it allows the engine to offer 570 CV, possible at 9,000 rpm. Power output meanwhile is measured to be 127 CV/liter. This allows the engine to set new standards not only for entire Ferrari range and its history but even for the whole market segment.

While maximum torque is pegged to be 540 Nm at 6,000 rpm, 80% of this is already available starting at 3,250 rpm. Specific torque meanwhile is 120 Nm/liter. It is important to note that what is really extraordinary is not the amount of torque made available. Rather high levels of power are maintained even at low revs. Paired to the engine is the dual-clutch seven-speed transmission which, even at full throttle, heightens performance while allowing for very smooth shifts. Because of the power and the torque curves deliver by the new V8 engine, the engineer made sure to develop sportier and specific gear ratios to match all of these.

This offers two advantages which are to guarantee high torque even when the engine is running at lower engine speeds and at the same ensure that the model can achieve peak speed in top gear. The sound that the new model emits is also what one can expect from a Ferrari model. There is that powerful and exciting roar which comes out from the engine before being channeled to the three tailpipes of the exhaust in the rear. The new Ferrari 458 Italia is also a big step forward as it relates to lowering emissions. It is clear that the new engine is more powerful when compared to the prior V8 engines. Combined cycle fuel consumption is 13.71/100 km, the best in the whole segment. CO2 emission meanwhile is at 320 g/km.
