GM gets the second entry in its electric armada ready as it faces troubling times

When it comes to GM, it’s hard to remove its financial predicament from news of its tech developments.  However, assuming that it can survive, GM has approved production of the Cadillac Converj according to a recent report.

Though some have poked fun at the name, the Converj has been quite popular ever since it was introduced as a Volt-derivative plug-in Cadillac concept at the North American International Auto Show 2009 in January.  The model seemed a logical move -- the Volt's production price is well above that of an average Chevy, but closer to that of a luxury brand model -- like a Cadillac.  By essentially re-releasing the Volt with luxury styling, the cost of deploying the Volt could be offset somewhat with an even pricier model under the Cadillac umbrella.

The vehicle has received official go-ahead from GM according a report from Motor Trend.  GM reportedly plans to unleash it on the roads in 2011 making it a 2012 model year vehicle.  Sources say that the Converj could even be the first profitable electric vehicle -- a major victory for GM, and a big boost in getting federal approval of their revised restructuring/bailout proposal, due June 1.

The source at GM says that the Converj will be followed up by a people-mover/crossover utility based on the Voltec (Volt) architecture. 

A GM spokesperson denied both comments, saying that no changes had been made with the Converj or other models.  However, Motor Trend stands by its source, stating.  The publication points out that the drivetrain (lithium-ion battery pack and 1.4L four-cylinder engine) could be largely reused from the Volt, with more battery mass added to give it more power.  The main work would be working an all-new sheetmetal and interior.

The new production model will reportedly be a two-door coupe, like the concept.  This is different from the 4-door with hidden handles version that retiring product chief Bob Lutz suggested.  The height of the production vehicle will also have to be tweaked to make production financially feasible.

The source says that they believe the Buick brand is a likely target for the people-mover.  GMC is another branding possibility.  The Voltec CUV would have two to three rows of seats

GM is continuing to make efforts to grow its profitable brands as it reluctantly agrees to kill other ones, as part of its restructuring -- including Saturn, Saab, and Hummer, according current expectations and reports.  GM has also entered into a partnership with Segway to release new light electric two-wheelers for urban streets.

adding a turbo would be pointless


Turbos increase Volumetric Efficiency, which increases gas mileage and Power for a given RPM. A larger could allow a bigger Generator thus charging the Battery pack in less time. allowing better MPG.

Sorry that was supposed to read:

The more air you cram into a cylinder the more fuel you have to use. The reason for putting more air into the cylinder is so more fuel can be used creating more power without degrading the mixture to the point of miss-fire / stall. Basically if you pile loads of fuel in a cylinder without the correct mixture of air, the engine will miss-fire and probably stall, but if you FORCE induction of air into the cylinder you can add more fuel use that oxygen to combust.

The only time that a turbo engine is as efficient as a N/A one is off the boost and if that is the case there’s no point adding the turbo!

However, I agree that a turbo would increase the power of the engine which in turn allows a bigger generator and reduces the recharging time. BUT the fuel consumption would go up!

Not always. If you read up on people who are putting the 4 cylinder diesel Cummins engines into just about everything, they increase their milage by adding a turbo and upping the power so they can in turn put in a better gear ratio. Producing more power can allow for a change in gearing that will produce the same speeds at lower RPMs, which can if done correctly actually use less fuel because you are using it more efficiently. Tractor trailer trucks and farm tractors use turbos more to increase fuel efficiency than to increase raw power.

Since we don't know the tweaks made to GM's battery charging engine it may be difficult to say whether a turbo, also tweaked, would be more or less efficient since we are comparing a different use of different engines.

Sorry, this is just plain wrong.
