Jaguar Spreading Threat for the BMW 3 Series and Mercedes C Class

1:10 AM carnews
Geneva, Jaguar XE finally announced as a premium medium sedan segment, once dismissed rumors that came before. This model is ready to go in a matter of months, and directly challenge the BMW 3 Series, Mercedes-Benz C Class, and the Lexus IS.



Interestingly, he came with a provision that claimed more sophisticated than its rivals. Most talked about is the aluminum monocoque chassis that will be used. Claimed, XE will be more efficient, luxurious, and advance.

Power of this car is supplied from the new engine gasoline or diesel. 2000cc capacity, complete with turbocharger. Exhaust emissions are very low, only 100 g/km of CO2. In addition, more fierce version will be offered, claimed capable of racing up to 300 kph. Of course, this model also has toned version as rivals, the BMW M3 or Mercedes-Benz C Class AMG, XER name.

Speaking at the Geneva Motor Show, (4/3/3014), Jaguar Land Rover’s CEO, Ralf Speth, said that the machines developed in Engine Manufacturing Centre, the UK would be a machine that is lightweight, low friction and emissions with a 4-cylinder configuration.

“The new engine will be used in all the latest Jaguar sedan medium. XE sedan called it will start to enter the production line later this year. Full specifications will be our recommend, and globally Jaguar XE will be sold mid-2015,” said Speth.

It is not yet official gliding, the prototype version is still kept, never appeared at the Geneva Motor Show. In addition to showing off the new model, this event was also used to search for consumer opinions about the XE.

Lamborghini Huracan LP 610-4 Geneva Auto Show

10:53 AM carnews



Lamborghini is aiming for “extreme levels of personalization” with a new customization program for the 2014 Lamborghini Huracan LP 610-4. Lamborghini has released a new promotional video for the Huracan. Set to be unveiled at the Geneva Motor Show on March 4th, the Huracan replaces the Gallardo and features an aggressive exterior that borrows cues from the Aventador and Sesto Elemento.


Power is provided by a 5.2-liter V10 engine that develops 610 HP (448 kW) and 560 Nm (413 lb-ft) of torque. It is connected to a seven-speed dual-clutch transmission and an all-wheel drive system which enables the coupe to accelerate from 0-100 km/h in 3.2 seconds and hit a top speed in excess of 325 km/h (202 mph). Word of the customization program, which currently is available for the Lamborghini Aventador, comes as the automaker launches the vehicle configurator for the Huracan.

All the excitement is being drummed up for the Geneva Motor Show debut of the 610 horsepower supercar, probably the biggest debut at this upcoming European venue. However “official debut” is only speaking figuratively, as the car has been shown to a number of customers across the world. Even Lamborghini admits at least 700 people have already placed orders already.

This is an excellent start for the Huracan LP 610-4, the high demand confirming the fact that people are extremely pleased with the design and the fact that 610 hp are now available from one of the most famous engines in the world, the 5.2 liter V10. Competitors to the Huracan LP 610-4 include the Ferrari 458 Italia and McLaren MP4-12C.

Lamborghini didn’t have much to say about the video itself but it appears to be a trailer for a film that will be released when the car is unveiled.

Fiat 500 Italia Uses Ferrari Engine

fiat 500 italia lazzarini design topFiat 500 small car did look adorable when noted. But what happens when a small car was fitted with a capacity of 4500 cc V8 engine Ferrari’s? Would certainly be unique!

Yes, the Italian Design Lazzarini who bothered to transplant the engine’s 4.5 liters of Italy to the Ferrari 458 Fiat 500 small car. Finally, this little car was no longer a small but tend scary other cars in the street.

Unfortunately, the Italian Fiat 550 was created only as a ‘training’ the crew Lazzarini. However, Lazzarini not rule out the possibility to immediately produce the car as long as there are investors who want to flush the fund of about U.S. $ 550,000 to take him home.

How not bertampak cute though, power is not seimut car looks. Because of the machines that have been placed in the back seat of power was able to burst up to 550 horsepower.

The engine power has actually been reduced because the real Ferrari engine could produce up to 570 hp tengaa, but the Fiat 500 chassis structure is considered safest to use force “only” 550 hp.

result is the name of the car had to be replaced. Lazzarini no longer use the name of the Fiat 500 for this car but the Fiat 550 racikannya Italy! For adjustment, Lazzarini also extended wheelbase car about 300 mm and 300 mm spread around his body at the rear and 200 mm in front.

The Car Heating System

2:29 AM carnews
Heat is a form of energy which means it cannot be destroyed. The principle of the heating and ventilation system is to transfer enough heat from one point to another. The heater is a device which heats the air entering or already inside the vehicle (recycled air). The heated air is then directed to a combination of different places via a distribution of air ducts within the vehicle.

Water cooling system
(with the agreement of Toyota (GB) PLC)


Heat exchanger



There are a number of different methods available to heat the air – exhaust heater, heat as a by-product of combustion, electric heater etc. Generally motor vehicles use heat from combustion which is transferred through water or air depending on whether the engine is water or air cooled. If the vehicle is air cooled then a system of shrouds is used to direct the heat from the external surface of the engine, exhaust or in some cases from the lubrication system towards the inside of the vehicle. 

Water cooled engines

The engine has a water cooling system which is used to maintain engine temperature by trans­ferring combustion heat (as a by-product of the combustion process) away from the combustion chamber. The heated coolant is then carried from the combustion chamber through pipes to a heat exchanger. 

The heater exchanger (heater matrix)


The heat exchanger (Heat exchanger), often called the matrix, is situated inside the vehicle housed
within the heater assembly (Water cooling system
(with the agreement of Toyota (GB) PLC)). It is designed to have a large surface area enabling air to

pass over the surface of its fins.Fresh or recycled air (air from inside the vehicle) is directed under force over the surface of the heater core and then distributed via air and panel vents into the vehicle’s interior. The heater core is made up of tubes and fins which are made from aluminium alloy and have aluminium or plastic tanks attached to the core with inlet and outlet ports.

Introduction to Heating and Ventilation

11:53 PM carnews
Heating and ventilation in automotive transport is not just a function of temperature control. The safety of occupants to reduce driver fatigue, ensure good visibility and maintain comfort is key to the successful design of such systems.A continual flow of air through the vehicle’s interior reduces carbon dioxide levels, acts as a demister and prevents the build-up of odours. Carbon dioxide in high concentration can cause a driver to be less responsive. There are recommended ventilation rates which specify the number of times the internal cubic capacity (air space) of the vehicle must be replaced per hour. Included in this calculation are the number of possible occu­pants and the internal volume of the vehicle. In some countries the performance of a heating and ventilation system is governed by legislation. The heating and ventilation system combined with an air-conditioning system provide a temperature range for occupants to select from. This can be a real challenge due to some extreme weather conditions experienced across the globe. Often auxiliary booster devices are required to provide additional ‘heating’ or ‘cooling’ of the interior.

The Design and Optimisation of an Air-Conditioning System

6:56 PM carnews


Case study – the air handling system

Experimental approach

In the past, the only way to evaluate a proposed air handling system design was to build a prototype and test it in the laboratory. The air handling components were placed on a test stand, conditioned air was supplied at the inlet and the airflow and temperature distribution at crit­ical locations were measured. This approach takes a considerable amount of time and requires the construction of expensive prototypes. In addition, it provides little or no understanding of why a design performed the way it did. In particular, testing is unable to detect details of recir­culating areas, turbulence, temperature stratification and constrictions that adversely impact performance and pressure loss. In addition, the performance of the system usually needs to be evaluated in many different configurations. For example, it sometimes is necessary to evaluate the air handling system in different modes of operation – vent, floor, defrost and mixed – at each of eight different temperature controls.

Modern methods of design


The design process of modern vehicle systems improved with the introduction of Computer Aided Design (CAD), Computer Aided Engineering (CAE) and Computer Aided Manufac­turing (CAM). CAD allows designs to be generated and visually appreciated on a computer. Standard components can be shared among manufacturers and suppliers to ensure that compon­ents assemble correctly. Designs can be sent to clients for verification and feedback. Designs can be modified and rechecked within short periods of time in a number of different formats, e.g. an STL file (stereolithography). Complex parts and assemblies can often be manufactured very quickly using rapid prototyping facilities (CAM). CAD also includes the facility to provide virtual testing. This is generally provided using additional modules or add-ins converting CAD to CAE. The software is even now used among a number of secondary schools in the UK who have the use of Solidworks as a CAD package for their technology departments which include add-in modules like Cosmos Works for Finite Element Analysis and Computational Fluid Dynamics. Finite Element Analysis (FEA) is basically mechanical stress analysis and Computational Fluid Dynamics (CFD) analyses the flow of a fluid like air through or over complex geometry. These additional features are all computer-based and use mathematical equations built into the soft­ware to predict variables like the stress distribution of a component or assembly (FEA) or the flow of air through an air vent (CFD). All these tests would have originally been carried out manually with continual adjustments being made to a model to optimise it.

Air pressure loss predicted by CFD


The process 

The A/C system begins life as an idea driven by consumer needs and government legislation. This leads to a specification. The specification will include minimum performance requirements, temperatures, control zones, flow rates etc. This will lead to a number of concept designs. The designs will have a number of computer generated models which will be presented as possible solutions to the original specification. These need to be tested for their performance. 

Performance testing using CFD may include fluid velocity (air flow), pressure values and tem­perature distribution. Using CFD enables the analysis of fluid through very complex geom­etry and boundary conditions. The geometry typically includes ducts that expand and contract, change from round to square cross-sections, go through complex curves throughout their length, and have many branches and internal walls. 

As part of the analysis, a designer may change the geometry of the system or the boundary conditions such as the inlet velocity, flow rate etc. and view the effect on fluid flow patterns. 

CFD is an efficient tool for generating parametric studies with the potential of significantly reducing the amount of physical experimentation required to optimise the performance of a design. 

A fan performance curve can be inputted into a model. Without this feature, the user has to guess the flow within the fan enclosure, calculate the pressure using CFD and see if it matches

the fan’s characteristics. If the pressure doesn’t match, then another guess has to be made. Normally, at least three iterations (test runs) are required to make a match.

The software has the facility to enter a fan performance curve directly into the model. Each analysis run then interacts with the fan curve to determine the precise operating conditions of the fan as part of the regular analysis. Using this technique, engineers can easily determine what

type of fan is required to meet air flow requirements within the vehicle, normally 158 cubic feet per minute (75 litres/second) for heating and 300 cubic feet per minute (141.6 litres/second) for cooling.

As a typical example of improvements consider the typical design specification of the HVAC system with respect to the temperature dial on the instrument panel. In other words, moving the dial from position one to position two should have the same impact on tempera­ture as moving from position two to position three. In the past, the linearity of the temperature dial could not be estimated until full vehicle prototypes were constructed.At that point, changes were costly and the testing data provided little or no input on what type of changes were required.


Prototype HVAC unit for testing


Now, engineers can determine the linearity of a proposed design as soon as the solid model in CAD has been created in a matter of days. They typically set up a series of analysis runs that evaluate eight different temperature settings at each of the three HVAC system modes. In less than a week, they can determine outlet air temperature at each setting. 

Once all CFD modelling is complete the prototypes are made to ensure the physical models operate as predicted by the computer models. The accuracy of simulated and actual system per­formance can vary up to 10–15%. Generally, lead times are reduced and designs can be evaluated much quicker allowing more time to optimise their working performance.

History of Automotive Air-Conditioning Systems

9:27 PM carnews
The early history of transportation systems starts mainly with the horse drawn carriage. This was eventually surpassed by the invention of the automobile. Early automobiles had cabin spaces that were open to the outside environment. This means that the occupants had to adjust there clothing to allow for different weather conditions. Closed cabin spaces were eventually introduced which required heating, cooling and ventilating to meet customer expectations. Early heating systems included heating clay bricks and placing them inside the vehicle or using simple fuel burners to add heat to the vehicle’s interior. Ventilation inside the vehicle was achieved through opening or tilting windows or the windscreen; vents were added to doors and bulkhead to improve air circu­lation and louvred panels were the equivalent to our modern air ducts. Air flow was difficult to control because it was dependent upon the vehicle speed and sometimes would allow dirty, humid air which contained fumes to enter the interior from the engine compartment. Cooling could be as simple as having a block of ice inside the vehicle and allowing it to melt! Eventually a number of design problems were overcome, these included air vents at the base of the windscreen for nat­ural flow ventilation and electric motors to increase the flow at low speeds. Eventually heat exchangers were introduced which used either the heat from the exhaust system or water from the cooling system as a source, to heat the inside of the vehicle cabin. Early cabin cooling systems were aftermarket sourced and worked on evaporative cooling. They consisted of a box or cylinder fitted to the window of the vehicle. The intake of the unit would allow air to enter from outside and travel through a water soaked wire mesh grille and excelsior cone inside the unit. The water would evaporate due to absorbing the heat in the air and travel through the outlet of the unit which acted as a feed to the inside of the vehicle. The water was held in a reservoir inside the unit and had to be topped up to keep the cone wet otherwise the unit would not operate. The air enter­ing the vehicle would be cool if the relative humidity of the air entering the unit was low.If the rel­ative humidity of the air was high then the water could not evaporate. When the unit was working effectively it would deliver cool saturated water vapour to the inside of the vehicle which raised the humidity levels.These units were only really effective in countries with very low humidity. 


In 1939 Packard marketed the first mechanical automotive A/C system which worked on a closed cycle. The system used a compressor, condenser, receiver drier and evaporator (fitted inside the boot/trunk) to operate the system. The only system control was a blower switch. Packard marketing campaign included: ‘Forget the heat this summer in the only air-conditioned car in the world.’ The major problem with the system was that the compressor operated continu­ously (had no clutch) and had to have the belt removed to disengage the system which was gener­ally during the winter months.Over the period 1940–41 a number of manufacturers made vehicles with A/C systems but these were in small volume and not designed for the masses. It wasn’t until after World War II that Cadillac advertised a new feature for the A/C system that located the A/C controls on the rear parcel shelf, which meant that the driver had to climb into the back seat to switch the system off. This was still better than reaching under the bonnet/hood to remove the drive belt. In 1954–55 Nash-Kelvinator introduced air-conditioning for the mass market. It was an A/C unit that was compact and affordable with controls on the dash and an electric clutch.

7:16 AM carnews





Thanks to the targeted empty weight reduction by about 200 lb, the combined average fuel consumption of the 4.0 liters V8 biturbo 4x4 bolide with 8 speed automatic gear has been pressed beneath 10 liters of gas. Because every customer has its own presentations of car sound, it is quiet obvious to offer kind of „sound by choice“. This is made by means of the HPERFORMANCE 70 mm double pipe exhaust system with two controllable exhaust valves. This system can be controlled optionally either pneumatically by overpressure or on electric ways via MMI. Besides „sounds by choice“, HPERFORMANCE offers an exhaust system with EEC type approval – surely an interesting fact for gentle clients from the European area.


By the way, the presented here RS6 has been equipped by the prototype of a carbon suction system, being very soon available on the market. The powerful up to 700 HP (= 515 kW) performance boost with 860 Nm of torque is due to the control device programming, not at all to supposed capacities of any boxes. We inform already now about the development of a new configuration level with modified downpipes, which will be available in the near future. As soon as this level will be achieved, HPERFORMANCE will offer still another upgrade level with bigger turbochargers. So, be curious
