First came electric steering (replacing hydraulic) on Giulietta and now potentially this. What's next, electric A/C compressor? Who knows the possibilities seem endless.

The French company Valeo presented during the event media Valeo Media Day, held on the German track, an ambitious project that aims to enhance the quality of 'Alfa Romeo Giulietta Quadrifoglio Verde, surely one of the finest pieces of the production of Alfa Romeo and one of the few sports in which variants really Alfa Romeo presents itself on the market today.

Valeo is developing a special supercharging system with electric compressor which aims to markedly increase engine performance by eliminating turbo lag that characterizes traditional supercharging system.  Valeo sported her this particular system by connecting through a series of structural changes, which according to Valeo would not be so deep as to prevent the installation of this system on all specimens in trade, to ' Alfa Romeo Giulietta QV with an outcome really very interesting.

L 'Alfa Romeo Giulietta QV, remember, can count on the valuable four-cylinder engine from the 1.75 Liter capable of delivering a maximum power of 240 hp, available at 5,750 rpm with a maximum torque of 340 explicated Nm, available in this case between 2000 and 400 rpm.  The draft Valeo translates in the installation of an electric compressor can provide additional 110 hp and 70 Nm of torque.  In total, therefore, the ' Alfa Romeo Giulietta QV suitably modified with this particular supercharging system is able to arrive at a maximum power of 350 hp, in this case available at 4500 rpm with a maximum torque of 410 esplicata Nm, available at 3500 rpm.

The basic version of the project involves the installation of an electrical system 12 V that allows a saving in fuel consumption for the 'Alfa Romeo Giulietta QV equal to about 10%.  This value can be increased by using a system 48 V, for example by using the same from Audi RS5 sull'Audi TDI, thanks to which the consumption could be reduced by 15-20%.  One of the strengths of the draft Valeo is to reduce the turbo lag due to the presence of the compressed electric which comes into operation well before the turbo mechanic, the response time is 250 ms, compensating a gap so really interesting.  We'll see if this particular system with electric compressor will come or not, over the next few months on the market.  For now we just have to highlight all of the interesting aspects of a project that could make it even more special Alfa Romeo Giulietta Quadrifoglio Verde.
The Alfa Romeo heritage "rinascimento" (renaissance) continues in each and every new model...the first "rinascimento" being 1915.

You can already get an electric A/C compressor as well as electric power steering on the Toyota Prius and Camry Hybrid vehicles. The reason being that the petrol engine is not running all the time hence the need for electric units. Toyota have had this technology for around 17 years now.

That means the first 6yrs of prius drivers had to do without A/C then...as it was first used in a car in 2003.

As for electric steering that first appeared 27yrs ago in the 1988 Suzuki Cervo, way before Toyota or any connection. But as we know a lot of things aren't "new" in the auto industry they just get either remarketed differently or become economically viable to produce at a later date.

The point is it's impressive (but accepting more complicated) to have more and more electrical devices on a modern vehicle, including solenoid operated inlet valve Multiair system(deleted cam) on 1.4Lt Giulietta striving to reduce emissions. And all this and still have a fun Alfa to drive with a basic electrical system of an alternator and battery essentially little changed in dimensions in over 30yrs.

That's all in stark contrast to battery laden hybrids with it's own electrical generator/engine/powerstation, supported by petrol engine to run things.
