Dreaded replacement battery problem for VW or Audi hybrid cars

One common misconception about hybrid vehicles is that their batteries will have dead cells and degraded battery life, requiring battery replacement after only a few years.  This is false!

What is the expected battery life of your VW hybrid or Audi hybrid?

Ruling out defects or other design issues and based off experiences with the first generation Prius, they should last a “lifetime”.  This is generally acknowledged by car engineers as 10 years or 150,000 miles.  However, there are many first generation Prius, not used for taxi service (which would build up high miles in a short amount of time), which have reached this point and are still running fine on their original batteries.

In addition, the VW Touareg hybrid has a 10 year, 100,000 miles powertrain warranty which includes the hybrid battery.  My guess is that this warranty might extend to other VW-Audi hybrid models.  In my opinion, it’s a good idea to instill confidence in your customers to move them into new technology and the warranty will help.

Will the real Audi A6 hybrid please stand up?

So which is the hybrid?  That’s one of the highlights of the Audi A6 hybrid.

Unlike many cars, the Audi A6 hybrid doesn’t shout “Look at me, I’m a hybrid”!  The new styling is bold and if you look closely you can tell which is the hybrid from the subtle badging.  Is this a turn off?  I don’t know because part of the sales success of the Prius other than competence is the fact that it looks like no other car.  A Prius is instantly identifiable as a hybrid.  The Honda and Nissan hybrids haven’t sold nearly as well even thought the Nissan licenses Toyota’s hybrid technology and system.  In fact, only the Prius can really be called a complete sales success.  In fact, if you asked most people what was the first modern hybrid sold in the US, you’d probably hear Prius instead of the correct answer, the Honda Insight.

So should Audi have followed the Hyundai Sonata’s example and given the A6 hybrid at least a different grille, headlights, and taillights?  The sales numbers will tell…

2012 Audi A6 hybrid no quattro, FWD only

At first glance, it looked like the Audi A6 hybrid would use the same engine and drivetrain as the Audi Q6 hybrid.  However, they’ve released further specs and information on the system and I can say that according to Audi’s news releases,

the 2012 Audi A6 hybrid will be FWD only.  There will not be a quattro option with the A6 hybrid.

Nowhere in their press materials does it explicity say that it will be FWD only and there will be no quattro hybrid but here are some clues in their releases:

“Audi will begin series production of the A6 hybrid, its second hybrid model after the Q5 hybrid quattro” – why didn’t they say A6 hybrid quattro?  This phrase is repeated in a number of places.

“The electric motor sits directly behind the TFSI [engine], occupying the space of the torque converter upstream of the modified 8-speed tiptronic. The transmission sends torque to the front wheels.” – the hybrid module is between the engine and transmission.  It says that there’s torque going the front wheels but not to the rear wheels.  Why not?

The other problem is one of space.  The car uses a gas engine just like the regular Audi A6 so it needs a fuel tank.  The hybrid module is under the rear trunk floor.  Maybe the rear half of the quattro drivetrain was omitted so that it wouldn’t intrude upon trunk space?  If so, that was a really boneheaded move.  They should have raised the trunk lid to give the car more room to fit the battery and keep a reasonable amount of trunk space.  I’m not saying that’s the reason, it’s just that it’s the only reason I can think of.  Hopefully this post will be proven wrong.  If not, they need to fix their press releases.

Is the 2012 Audi A6 hybrid the most luxurious hybrid ever? A review.

The new 2012 Audi A6 hybrid specs and photos were just released and the car contains many state of the art infotainment and luxury features.   Is this the most luxurious hybrid ever?  Probably not. Lexus made a 600h, a V8 powered hybrid tank. It was really designed as a replacement for people who would otherwise buy a V12 and decided they would go green with the V8 instead of buying a smaller, lighter car.  In my opinion, the vehicle iss the classic example of greenwashing.

The engine in the Audi A6 hybrid and performance

The mpg rating on the Audi A6 hybrid could be better and I’ll bet most people would be perfectly happy with a slower car, so while I think Audi could have given a small mpg boost to the Audi A6 hybrid, it’s a much, much better balance between performance, weight, and fuel economy.  The engine combines a 2.0L turbocharged engine with a hybrid motor.  0-62 mph is around 7.3 seconds so while it’s not a fast car, most people would find a car with a 0-60 time of around 10 seconds acceptable for performance on public roads.

What engine could be better?

What engine could have given similar performance with better fuel economy?  VW-Audi’s engine stable includes a 1.4L turbo and supercharged engine which is used in cars all the way up to the Passat which is only slightly smaller than the A6.  This engine is not equipped on any car in North America because while it’s small, packing all that premium technology into a small engine is expensive and people in North America want big, cheap cars.  It makes 122 hp and 148 lb-ft of torque at only 1500 rpm.  So while you won’t win any drag races, it has plenty of low end power because of the turbo and supercharging.  Combined with the electric motor module, this smaller engine could have produced better fuel economy through smaller weight, displacement, and start up times, with good performance.

So while there’s room for improvement, the Audi A6 hybrid is probably the best combination of power, performance and efficiency available in North America….now where are those TDI diesels that they’ve promised us!

2012 Audi A6 hybrid confirmed to have lithium ion batteries

It looks like the Audi a6 hybrid will definitely get lithium ion batteries.  There was some question over the exact drivetrain configuration since VW-Audi-Porsche use a few hybrid drivetrains.  Would it be like the Porsche Cayenne and VW Touareg hybrids with a 3.0L engine and nickel metal hydride batteries or the Audi Q5 hybrid with a 2.0L engine with lithium ion batteries.

Well, it looks like they’ll make things simple for the mechanics and parts factory and stick with the 2.0L engine with lithium ion batteries.

While it doesn’t sound like a lot of power, it’s combined with an 8 speed transmission to yield a 0-62 mph time of 7.3 seconds which is more than fast enough for an economy car.  The Audi A6 also uses plenty of aluminum in its structure to lose weight.

Audi A6 hybrid will be the second audi hybrid car

The first new Audi hybrid car will be the Audi Q5 hybrid but it was unknown if the next one would follow up with the Q7 hybrid concept or another model.

It’s now confirmed that the Audi A6 hybrid will be the next hybrid model in Audi’s lineup.

While early hints suggested that it would use a 3.0L supercharged engine it’s now known that it will use a 2.0L turbocharged engine like the Q5 hybrid.  The total power will be 245 horsepower but the torque is unknown.  Since it looks like the engine is the same as the Q5 hybrid’s, it should be 354 lb-ft which is quite a lot.   To put that in comparison, that’s more torque than the current 4.2L V8 engine!  Needless to say, with only 245 horsepower you won’t win drag races against sports cars but the car will have no problem getting out of its own way.

0-60 is projected to be about 7.2 seconds which isn’t super fast but it’s more than enough for daily driving.  Remember that a common 0-60 time for older cars used to be around 10 seconds and some of the slower cars today still linger around 9 seconds.  6 seconds would be sports car territory and remember that it’s more fun to drive a slower car fast than a faster car slow.
