Modification authorities in India - DC DESIGN

DC Design is an Indian design firm from Mumbai which is noted for their concept cars and prototypes. The firm, founded in 1993, is headed by designer Dilip Chhabria, and under a contract with Ford Motor Company built the first Aston Martin AMV8 Vantage prototype featured at the 2004 Detroit Auto Show.^[1]

The company also builds custom special order vehicles,^[2] such as a modified Porsche Cayenne coupe,^[3] and a modified Rolls Royce coupe.^[4] In August 2006, the company announced a partnership with Eximstar, an ETA Group company, to build a 500,000-square-foot (46,000 m²) production facility in Dubai.^[5] The facility, scheduled to open in 2007, will produce custom luxury cars.

Dilip Chhabria is an Indian automobile designer. He is the founder of DC Design.

He is qualified in Transportation Design from the Art Center College of Design, Pasadena, California, U.S. and worked with General Motors USA in their Design Centre. He also started his own auto accessory business and became one of the largest auto accessory manufacturers in India.^{[citation needed]}

His company made the first prototype for the Aston Martin Vanquish which appeared in the James Bond movie Die Another Day.^[1]

In 2006, Chhabria announced DCStar, tie-up between Eximstar (an ETA group company) and Dilip Chhabria Design Pvt Ltd. The company, to be set up in Dubai, will customize cars and other vehicles to suit customers' requirements.^[2] He has designed Vanity Van for many stars such as Sanjay Dutt, Shah Rukh Khan. He has also designed the car used in the movie Taarzan: The Wonder Car directed by Abbas-Mustan. In 2010 he designed a special version of Tata Nano. In August 2012 DC gave a complete external and internal make over to Mahindra XUV 500 with seating chairs made to recline up to 150 degrees and enhanced lounge lighting.^[3] In August 2013 DC released the second generation of DC Lounge Fortuner, a special body kit for the Indian version of Toyota Fortuner. This was India's first full body altering kit for any car commercially available for 7.25 lakhs.^[4]

He also runs a special Automobile Designing Institute called as DC - DYP in association with Dr D Y Patil University in Pune, Maharashtra. His latest invention is 'DC AVANTI', the most economical sports car costs nearly 25,00,000 Indian rupees which is about 50k dollars.

DC Avanti is the first Indian designed sports car by DC Design, a firm headed by Dilip Chhabria. DC Design has previously been known as a tuner of other's vehicles; this will be their first foray into producing a complete automobile. Taking its name from the Studebaker Avanti of The Adventures of Tintin comics,^[1] it was unveiled at the 2012 Auto Expo Delhi as a two-seat sports car. It will initially be equipped with a mid-mounted, Ford-sourced, 2.0-litre four-cylinder turbocharged petrol engine producing 261 bhp, A Honda-sourced V6 version with 394 bhp is planned for future release. Transmission is a six-speed dual-clutch transmission. The Avanti weighs 1562 kg (3440 pounds, or more than a Chevrolet Corvette), and features extensive use of aluminum. Its makers, who are based in Pune, claim the base model will hit 62 mph in less than seven seconds.^[2] Plans are to release the car for sale in 2013.^[3] The manufacturer plans to build 200 cars a year, hoping to raise output to 2000 cars a year in the future.

The DC Avanti is expected to be priced around INR 30 Lakhs,^[2] approximately $56,000 in US dollars.^[4]

he Toyota Innova is a Toyota-designed Compact MPV i.e. being less than 4,600 mm (181.1 in) in length as per the European system of size classification, produced in Indonesia under supervision by Toyota Astra Motor since 2003. As with Toyota Kijang, which it replaced, the Toyota Innova is produced and first marketed in 2004 in Indonesia. Toyota Innova is part of Toyota's IMV program together with the Hilux Vigo pickup truck and the FortunerSUV. Its official name in Indonesia is Toyota Kijang Innova, while for other countries it is Innova.

Once you step inside the Toyota Innova, you will find that the maker has retained the adequate space that had been provided in the earlier model. Just have look on 2012 Toyota Innova Modified by DC - Limited Version

A modified car consist of any of the components associated with car tuning, however common upgrades include replacing the standard factory issue wheels with aftermarket alloy wheels, usually of a larger diameter to improve the aesthetics; lowering the suspension of the car to give it a more aerodynamic, stable look by replacing the springs (often in conjunction with shock absorbers) or torsion bars; replacing the existing exhaust system with one with less gas-flow restriction, louder and deeper sound and often small improvements in performance (due to exhaust gas-flow rate). Other common upgrades include the installation of a short shifter as well as an aftermarket shift knob, or a performance oriented Weighted Gear Knob. Common non-mechanical upgrades include a cars audio system; though not performance oriented, are nevertheless a very common-place modification. This includes upgrading the head unit itself, and upgrading and/or installing additional speakers.

Significant modification to a car could involve adding a fiberglass body kit to improve the aesthetics, a complete respray to a more unusual, distinctive and noticeable colour and finish, increasing the engine performance with ugraded components such as a high-flow air filter, additional components such as turbocharger, supercharger, Nitrous oxide kits, aftermarket cylinder heads or porting and polishing of O.E.M. heads which require retuning of electronics (later model vehicles - fuel injected) and modifications to vehicle sub-frames to accommodate additional horsepower caused by said changes. Traditional customizing methods, more common when modifying classic cars to create cars such as Hot rods, include roof chops, two door stretches, suicide & lambo doors, channeling and lights, trim and sheet metal from another car. Sectioning is also used sometimes.

The essence of modification of a tuner car is an attempt to extract the greatest possible performance—or the appearance of high performance—from the base motor vehicle through the addition, alteration or outright replacement of parts. Although this largely involves modifying the engine and management systems of the vehicle to increase the power output, additional changes are often required to allow the vehicle to handle this power, including stiffened suspension, widened tires, better brakes, improved steering and transmission modifications such as the installation of a short shifter. Although largely invisible from outside the vehicle, certain modifications such as low profile tires, altered suspension, and the addition of spoilers can change the overall appearance of the car, As well as adding downforce to increase traction.

Engine tuning is the process of modifying the operating characteristics of an engine. In a typical engine set-up, there are various mechanical and electronic elements such as the intake manifold, spark plugs,Mass air flow/ Volume air flow, etc. Modern engines employ the use of an ECM to provide the best balance between performance and emissions. Via the OBD communications protocol, the electronically controlled aspects of the engine can be modified in the process known as 'mapping'. Mapping can either be performed by changing the software within the ECU (chip tuning via firmware modification), or by providing false data via plug-in hardware (piggybacking). Mechanical components can also be replaced, such as turbochargers or superchargers.

Other standalone engine management systems are available. These systems replace the factory computer with one that is user programmable.

Poorly executed modifications can have a detrimental effect on performance as well as mechanical and electronic components. An example would be the use of an air compressor such as a turbocharger to increase the volume of air used in power stroke of the otto cycle. In a typical chemical reaction, the air-fuel ratio must be a minimum of 14:1 (see Stoichiometry). If higher ratios are used, higher pressures and temperatures are observed in the cylinders. Depending upon the build of the engine, such operating parameters can lead to premature failure such as warped cylinder heads and walls (temperature related), cracked connecting rods and crankshafts (excessive torque applied), engine seizing and blowouts.
