Polo GTi to India in March 2016

As CARWALE reported earlier the VW Polo GTi was spotted testing in Pune recently. It is expected to be launched by March 2016.

The Polo GTi is powered by a 1.8l TSI petrol engine producing 180hp and a maximum of 250Nm torque. The same engine is used Abroad, to power Audi A3 and Skoda Octavia. The polo GTi might also have a 7-speed automatic transmission. To match for the power, the suspension and the brakes are also beefed up. The price range for this car might be of 9.95lakhs to 14 lakhs.

History of the Raging Bull

Automobili Lamborghini has always been my favorite super car manufacturers. Many new boys like the Pagani, Koenigsegg have tried to slam down Lamborghini, but, no matter what Lamborghini have always been on top. They have been the favorite bedroom wall posters for the petrol heads for more than 5 decades. Now lets take a look into their history.

Ferruccio Lamborghini was an Italian Industrialist who founded Lamborghini Trattori, which very soon became a successful agricultural equipment manufacturer. Lamborghini's increasing wealth made him buy enough car so that he could use a different car on every day of the week. He owned Alfa Romeos, Lancias, Mercedes-Benz 300SL, a Jaguar E-Typecoupé, and two Maserati 3500GTs. In 1958 Lamborghini travelled to Maranello to buy a Ferrari 250GT. Lamborghini thought Ferrari's cars were good but were noisy and too rough to drive as a road car. Lamborghini found that Ferrari's cars were equipped with inferior clutches, and required continuous trips to Maranello for rebuilds; technicians would secret the car away for several hours to perform the work, much to Lamborghini's annoyance. He had previously expressed dissatisfaction with Ferrari's aftersales service, which he perceived to be substandard. Lamborghini brought his issue to Enzo Ferrari's notice. But Enzo Ferrari dismissed his thoughts about his car and said a tractor manufacturer had no right to complain  about his cars.

Lamborghini was disappointed. He decided he would start a company, manufacturing cars which are better than Ferrari's, to prove him wrong. The rest became history. 

Automobili Lamborghini was founded on October 1963. They started manufacturing Luxury Super cars unlike the Ferrari's. The company gained wide acclaim with Miura, which is the world's first Mid-Engine Super Car.

Lamborghini's has been a real threat to Ferrari's. They have a soul that the Ferrari doesn't have. The flat shaped, breath taking designs are great sight anywhere in the world. The current master piece leading the race for Lamborghini is the Aventador, which will be the last car with the Lamborghini DNA ( naturally aspirated  V12 engine).

How does fuel economy work?

In all automobiles there is a speed range for the fuel economy run. Do you know how exactly it works?

First lets see what air fuel ratio is. As from Wikipedia Air–fuel ratio (AFR) is the mass ratio of air to fuel present in a combustion process such as in an internal combustion engine or industrial furnace. The AFR is an important measure for anti-pollution and performance-tuning reasons.

If exactly enough air is provided to completely burn all of the fuel, the ratio is known as the stoichiometric mixture, often abbreviated to stoich.

AFR numbers lower than stoichiometric are considered "rich". Rich mixtures are less efficient, but may produce more power and burn cooler, which is kinder on the engine. AFR numbers higher than stoichiometric are considered "lean." Lean mixtures are more efficient but may cause engine damage or premature wear and produce higher levels of nitrogen oxides.

For precise AFR calculations, the oxygen content of combustion air should be specified because of possible dilution by ambient water vapor, or enrichment by oxygen additions.

Your vehicle get maximum fuel economy when the engine is using the right amount of gas. Fuel for automobile is a mixture of air and petrol/ diesel. So for the perfect fuel economy, you vehicle should be running at  a particular speed where the engine gets the right ratio of air and gas mixture. Lets say the economy range is 45kph to 60kph.

1. When the speed is less.

When the vehicle speed is less than the economy range there is less air passing in through the intake so to compromise to the ratio more gas is consumed.

2. When the speed is more.

When the speed is more than the economy more air is passed in through the intake and in order to prevent lean mixture more fuel is supplied.

3. Economy range.

In the economy speed range right amount of air is supplied into the engine and thus right ratio of fuel with the best fuel efficiency is provided.

Driving in the fuel economy range is good for not just the engine, its good for the future, its good for environment and its good for your bank account.

BMW M2

The much anticipated all new BMW M2 is finally here.

This is one of the most beautiful looking coupe. The M2 has a more aggressive look than the M235i. The all new bumpers with 3 air dams and the rear end features a discreet trunk-mounted spoiler and four exhaust tips integrated into an air diffuser that’s painted gloss black.

All new 19-inch light weight forged rims with Michelin pilot super sport tyres give better road grip and road holding ability.

 Now lets talk about interior. The interior is spectacular.

M2 gets a three spoke steering wheel designed by the BMW's M division, sporty leather seats with blue stitching,adjustable side bolsters and an M footrest and knee pad on the center console for the driver. The M logo is sprinkled throughout the cockpit. Carbon fiber dashboard adds to the sporty touch.

Now lets take a look at the engine.

The M2 is powered by a 3-liter turbocharged six cylinder engine producing 370bhp and 465Nm torque and this torque can be increased to 500Nm with over-boost function. The M2 can reach 60mph from 0 in 4.2 seconds using the 7-speed automatic gearbox.

Expected price in India should be somewhere around 50 lakhs

Supercharger and Turbocharger

What is Supercharging and Turbocharging?

A supercharger is a turbine that compresses the air supplied to the ICE ( Internal Combustion engine) and thus increases the pressure and density of air supplied to the engine. Therefore more oxygen is supplied to the engine during each intake cycle, letting more fuel burn and there by increasing the power output. The power for the working of turbine is obtained from the working of engine via a belt, gear, shaft or chain.

Supercharger

There are mainly two types of supercharger, namely, Positive displacement and Dynamic compressor .

Positive displacement compressor provides a constant and a fixed amount of air at all speeds. Therefore the power is available during every revolution.. Whereas Dynamic compressors rely on accelerating the air to high speed and then exchanging that velocity for pressure by diffusing or slowing it down. That means, dynamic compressors do not provide pressure at low speeds. As speed increases above a certain rpm the power get delivered( usually called as power lagging).

Whereas, the key difference between turbocharger and supercharger is that the power for the turbine in turbocharger is obtained from the exhaust from the ICE

Turbocharger

A turbocharger is more efficient, provides more power and produce less emission than a naturally aspirated engine. The turbocharger is less responsive than a supercharger. Turbocharger is commonly used in Petrol and Diesel engines but they are also found useful in fuel cells. Because they are smaller in size and less complicated, they are more preferred. 

Apart from these, a twin-charger refers to an engine using both supercharger and turbocharger. 

Supercharging and turbocharging are widely used these days as they are fuel efficient, provides more power and produce less emission.
