One lap only: Fisker Karma takes on Laguna Seca in public driving debut [w/VIDEO]

by Sebastian Blanco (RSS feed) on Aug 17th 2009 at 1:56PM

The world driving debut of the Fisker Karma happened at the Mazda Raceway Laguna Seca on Saturday. Our compadres at Autoblog were snapping photos of the glut of luxury cars all weekend long, but almost missed the Karma. How could you miss a car like this? Well, it drove around the corner so silent they didn't hear it coming and then is only made one lap. The original plan was to sent the Karma around twice. Still, quick shutter release fingers mean we have a few images of the drive to share with you. Check out the Karma on the track in the gallery below along with a shot of the car at Concorso Italiano over the weekend then hit the jump for the sights and sounds of a luxurious Laguna Seca lap from behind the wheel.

Supposedly it has a GM turbocharged 2.4 to charge the battery. So I guess it's not out of the realm of possibility that was a BOV venting. Seems kinda boy-ricerish on a $70,000 car though.

From my understanding the Fisk has the 2.0DI Turbo to charge the batteries. So of course your going to hear a blow off valve. Oh and with all the money sunk into this thing and their deadline is to beat the Volt to market. To be honest, i hope this thing actually comes out.

Awesome, I saw them driving it up the main street in Carmel that same evening! I ran out into the middle of the street to take a pic of them, but everyone was expecting that kind of insanity on the whole Monterey Peninsula this past weekend.

I definitely hope it gives the Volt some competition, but I'm saddened it's not pure electric, or at least optioned with a no-ICE package.

they actually said " the Karma will set you back 87000 dollars, but think of the money you will save on gas"

its that kind of stupidity the EV movement does not need. Lord knows I am not a huge fan of these types of cars, but do not insult the buying public.

I just do not see the point. I can get a 4 door M3 which is faster accelerating, braking and still have 20 grand left in my pocket for all that pricey gas.

Still, I want to give Fiskar Kudos for making it easy on the eyes!

Yah, that was a dumb line.

This is more of a 5 series, A6, E class competitor. Only smoother and much quieter. Supposedly they got up to 100mph in that first video...

Sounds like a lot of tire noise or something like that when hes taking some of those corners....

Why would you be saddened by that? The ICE helps extend it's range. These are all 1st-gen cars out there - when battery tech is far enough along to give you a reasonable range, you better believe that the "backup" ICE will go away, but you gotta learn to walk before you can run.

The motor is the GM Ecotec 2.0l DI turbo similar to Cobalt SS.

Vehicle can run on electric only. ICE is there for extended range.

And until batteries can give more than 200 miles and charge times of around 15 minutes, all electric won't work for me.

Why does a battery charging ICE need to be turboed?

More power = more electricity to charge with. It's only running part-time... so it should be able to run up to wherever it hits peak torque and stay there long enough to recharge the batteries. If it works for all the turbo diesel electrics out there.. why not a small gas/electric?

I guess so, but it would seem a small one liter engine would be sufficient. I mean how much power can it take to turn a generator. It must not be trivial is all I can guess.

The long-term average power demand of the car needs to be matched by the generator's output or you gradually deplete the battery to zero.

In performance driving, the average demand can easily be 200 HP...

The small 1-liter wouldn't have enough torque available to recharge the batteries. When your applying a current through the generator it's added resistance, and the torque of the Turbo'ed 4 cyl. is obviously enough to overcome and recharge the batteries.

I guess that depends on how efficient your generator is.

It'd do fine, it would just take longer. I expect we'll see 500cc singles in EREV's before too long. For most driving in a small, light car, 30 hp is plenty as a long term average power supply.

If you draw 200 hp from the battery for 15 seconds to get to 75mph, and then draw a steady 20hp to cruise at 75, then it would take say 4.25 minutes for that 30 hp motor to put that amount of electricity back into the battery (with the 10hp surplus we have )and then the engine could ease up to produce just the currently needed 20 hp.

Fine in a commuter car, not so hot in a premium performance EREV...

Well of course a smaller engine will work for a smaller car but I was thinking solely of the Fisker's layout.
With (2) 200 hp equivelant electric motors I would see the need for a larger ICE, plus the added benefits when the Fisker is in "Sport-Hybrid" mode with the more powerful engine.

Some amount more than however much power you want to come OUT of the generator.
