Fisker Suspension

Edmunds has a very nice photo review of the Fisker Karma suspension.

My takeaway: heavy car, expensive chassis, very complex.   But also very impressive, considering the complexity of the machine.   Tesla, for its Roadster, let Lotus take care of the chassis and suspension design and had to focus mostly on the powertrain.

I will be amazed if Fisker makes enough money to stay in business with this model.

Cadillac 4 Cylinder

This is what the world has come to.   GM is putting a four-banger in a Cadillac.  

But this isn't the I4 of old, this is a modern, direct injected turbo with variable cam timing.  The GM 2.0L Ecotech makes 270HP and 260lb-ft of torque.  It is a similar engine to the Ford 2.0L Ecoboost which is now the fuel economy option for the Explorer. 

By comparison, the FWD versions of the famed Northstar engine family (LD8) made 275HP and 300ft-lbs, out of a whopping 4.6L of displacement.

iDrive Prank Box

I was sent this prank gift box, which is hilarious.




It is designed to look like a believable (but crazy) product, the iDrive, which is a suction cup and claw mount to mount iPads and other devices on your steering wheel or other unsafe places.  Photos on the back show it being used in cars, on a factory runabout and also on a jet ski. I wonder, though, how the box maker gets away with using "iDrive", which is a real trademark for a number of different types of products, including data storage and surgical staplers.




The actual product is the prank box itself, one of many that are sold by Prank Pack.

I am going to use it on a friend, who is both a car nut and a Apple cultist.

Old People Cars

According to the Detroit News, this is the list of most popular vehicles for senior citizens.  I have added additional information: which models are discontinued.

1. Lincoln Town Car, 90%

2. Buick Lucerne, 87%

3. Cadillac DTS, 85%

4. Cadillac CTS, 74%

5. Cadillac STS, 71%

6. Hyundai Azera, 25%

7. Chevrolet Impala, 51%

8. Buick LaCrosse, 59%

9. Lincoln MKZ, 54%

10. Toyota Avalon, 54%


The interesting question to me is, what will the old folks buy now that the softly spring boats have mostly gone extinct?

Bridgestone Airless Tire Concept

Cool.  From PhysOrg.com.

Michelin has also been working on the Tweel airless tire for some time now, but it isn't ready for civilian commercial sale, yet.

Volt Battery Fires NBD

The blogosphere and news media have become somewhat excited about the Chevy Volt battery fires, and GM has been very defensive, going so far as to offer to buy back Volts from any skittish customers.

I don't see what the big deal is.

There zero cases of Volts having battery thermal issues after getting in an accident in the real world.  There have been a couple of cases of garage fires, however the causes are not yet known and it is quite possible that the fault lies in poorly done 240V wiring, and not with the Volt.  

There are four cases of Volt batteries having thermal reactions after being first disconnected from their liquid coolant supply, then damaged, and then overturned by NHTSA.  This is like sideswiping a pole at high speed, at exactly the point where the battery extends out towards the sides of the car, then rolling over, and then letting the battery sit damaged for several days without being discharged.  

Here's an experiment: smash a gasoline car in such a way as to rupture the gas tank. Then turn the car over and let the fuel run where it will.

Also, consider the number of gasoline vehicle fires that occur every year.  In 1999, there were 288,000 highway vehicle fires, due to all causes (accident and otherwise), according to the NFPA.  According to a 1990 study by NHTSA, motor vehicle fires due to accidents occurred at a rate of 2.86/1000 vehicles. 

So if Volts had the same rate of accident caused fires as gasoline vehicles, we would expect to see about 14 Volt fires this year.  But we haven't, even though Volts do carry gasoline on-board.

Aptera Dead!

I have been watching with morbid fascination the death spiral of Aptera, the designer of the electric trike that looks like a big spermatozoan, which didn't do well in the Progressive Automotive X-prize competition.  To stave off death, Aptera was working on a traditional 4-wheel vehicle concept which they hoped would attract new investors and help them qualify for a DOE AVTM loan.  Aptera stated that they needed $150 million in new money to start work on the new vehicle, but investors did not come to the table.

And that was a wise decision.  Despite an interesting and aerodynamic design, the Aptera 3-wheel concept was not practical for any large market, and would have been very expensive to produce in small volumes.   Like the other X-prize finalists running 3-wheel designs, Aptera was more of a design study than a marketable product.   

To date, there are still no production-ready enclosed 3-wheelers for sale in the U.S. and I doubt there will ever be.  The inherent safety and comfort trade-offs are too great for more than a few novelty-loving customers.

The question in my mind is, who is next to fold?  Up-start auto companies funded by venture capital don't have a shining history (DeLorean, Bricklin...).  Will Tesla and Fisker make it, financially, or will they burn through their cash before catching on?

How To Reset Your Garmin

I needed to reset my Garmin 1390 GPS unit, before giving it to a friend, to erase all of my personal data.  I found out there is a nice factory reset function which will clear all user data.

To factory reset your Garmin:
  • Power off the unit
  • Press and hold the lower right corner of the screen
  • Power on the unit.

I also found that if you do the same thing but press and hold the upper left of the touch screen, it will re-calibrate the touchscreen.

NHTSA: Volt Battery Pack Post Crash Risks

NHTSA posted a press release on its web site which explains its recent test results with Chevy Volt batteries.

In an effort to recreate the May test, NHTSA conducted three tests last week on the Volt's lithium-ion battery packs that intentionally damaged the battery compartment and ruptured the vehicle's coolant line. Following a test on November 16 that did not result in a fire, a temporary increase in temperature was recorded in a test on November 17. During the test conducted on November 18 using similar protocols, the battery pack was rotated within hours after it was impacted and began to smoke and emit sparks shortly after rotation to 180 degrees. NHTSA's forensic analysis of the November 18 fire incident is continuing this week. Yesterday, the battery pack that was tested on November 17 and that had been continually monitored since the test caught fire at the testing facility. The agency is currently working with DOE, DOD, and GM to assess the cause and implications of yesterday's fire. In each of the battery tests conducted in the past two weeks, the Volt's battery was impacted and rotated to simulate a real-world, side-impact collision into a narrow object such as a tree or a pole followed by a rollover.

So in short, NHTSA is crashing Volts with  very specific protocol--a narrow pole, which will cause severe deformation/penetration of the body structure, followed by a rotation to simulate a rollover.

The batteries aren't catching on fire right away, rather they seem to take some time to build up heat.  

I don't think there is anything to worry about, yet.  First, this is a very specific and severe type of crash, and second, it takes hours or days before the battery self-heats to the point of fire.  As NHTSA and GM both point out, no on-the-road accidents are known to have caused battery fires.

However, GM apparently was late to the game, by not developing beforehand a procedure to discharge (and render safer) the Volt battery.  They are now rolling this procedure out to first responders, who need to know how to neutralize a charged lithium ion battery after a severe accident.

Review: Davis CarChip Pro

This is a review of the Davis Industires CarChip Pro . 


The CarChip is a small device which plugs into your vehicle's OBD-II port, and acts as a datalogger.  It can record vehicle speed every second, and up to 4 other items at a slower rate of one sample every 5 seconds. Retail prices are around $80.

The device is simple to configure.  Once you install the software (which worked fine on Windows 7), and plug the CarChip in with a mini-USB cable (included), a step-by-step configuration walks you through the initial setup.




For example, you can choose to record 4 parameters at every 5s, from a choice of several standard OBD-II parameters, including engine speed, throttle position, engine coolant temp, engine load, air flow rate, spark timing, air/fuel ratio, battery voltage, and oxygen sensor voltage.  You can also set audible alarms, to have the device beep at you if you exceed a top speed, or a max accel/decel rate.


For my testing, I plugged it into my 2007 (which would be using CAN OBD-II), and drove a few trips.  I also induced two powertrain diagnostic faults: I loosened my fuel cap, and for a short time, disconnected my intake air temp sensor (IAT).


After removing the device and downloading the data to my PC, I was able to use the software to plot the recorded channels, and the device properly logged two DTCs, one for evaporative emissions (P0456) and one for the IAT circuit test failure (P0113).  By clicking on a menu choice, you can tell the CarChip to clear the codes next time you plug it into your vehicle.





Overall, I liked the CarChip, and I would recommended for several use cases.  A hobbyist or fleet owner who wants a low-cost way to log mileage, driving style, fuel economy, etc. would do well with a CarChip if they don't mind plugging into it every so often to download the data.  It could also be useful to someone who wanted to program it as a "trainer", to teach themselves (or their kids) not to accelerate too hard or brake too abruptly, to teach a high fuel economy driving style.

However, I wouldn't necessarily recommend this as a primary diagnosis tool, for example to debug DTCs or do performance tuning, because of its offline nature.  Someone who wanted to quickly determine why they have a Check Engine lamp, and perhaps check some of their engine control sensor values as part of the debug would be better off with an interactive scan tool.  Also, the relatively slow 5s sampling rate may cause users to miss some aspects of the engine performance, such as sudden lean fuel excursions or speed fluctuations.

My advice to Davis, to improve this product, would be to add a "live mode" which pulls the OBD data in real-time via the USB, and to add some sort of wireless interface so that the data can be monitored and downloaded via bluetooth without having to plug into the unit directly.

Pros:
  • Simple to use software, easy setup
  • Ability to set speed/accel/decel alarms
  • Fault code logging and clearing
  • Small, unobtrusive
  • Data can be easily exported
Cons:
  • Slow sampling rate (5s) on user-configured data channels
  • No apparent "live mode" to look at data interactively, while connected
  • No wireless transfer mode (bluetooth or wifi).
* Davis provided me with a sample unit, however I recieved no compensation for this review.

Coda: Does Anyone Care?

The Coda is an all electric sedan built on a Chinese copy of a Mitsubishi compact sedan chassis, stuffed with batteries and electric motors.  It looks cheap.  But it will cost $40,000 like the Focus BEV, Chevrolet Volt, and Nissan Leaf high trim model.  

Does anyone really want one at this price?

New Fiat 500 Abarth Commercial

Awesome.

Translation from a YouTube viewer:

What are you looking at? Uh!?

What are you looking at?! (slap)

Are you undressing me with your eyes?

Poor guy…you can't help it?

Is your heart beating? Is your head spinning?

Do you feel lost thinking that I could be yours forever?

Smelly Anarchists Begone!

NYC has finally had enough of the Occupy Wall Street crowd in Zuccotti park.  A judge has denied a lawsuit for a restraining order against NYPD, on the grounds that

To the extent that  City law prohibits the erection of  structures,  the use of  gas or  other  
combustible materials, and the accumulation of  garbage and human waste in public places, 

enforcement of the law and the owner's rules appears reasonable to permit the owner to maintain its 
space in a hygienic, safe, and lawful condition, and to prevent it from being liable by the City or  others 
for  violations of  law, or  in tort.  It  also permits public access by those who live and work in the area 
who are the intended beneficiaries of  this zoning bonus.  
 
The movants have not  demonst rated that  they have a First  Amendment  right  to remain in 
Zuccotti Park, along with their tents, structures, generators, and other installations to the exclusion 
of the owner's reasonable rights and duties to maintain Zuccotti Park, or to the rights to public access 
of  others who might  wish to use the space safely
. Neither have the applicants shown a right to a 
temporary restraining order that would restrict the City's enforcement of  law so as to promote public 
health and safety.

Presumably, now the NYPD will begin moving the squatters out of Zuccotti park, so that the damage can be repaired.

EVs Should Be Loud

Today, while crossing a busy grocery store parking lot, I was really startled by a silent Prius driving accross my path.  Since I didn't hear a noise, I didn't expect to see it moving near me.

I'm coming down on the side of noise pollution here.  EVs (BEVs or HEVs in electric mode) should make some sort of noise, loud enough for a pedestrian to hear within about 15 feet or so.  Silent cars are not as safe.

The End of Saab (Again)?

This might be the be the end for Saab.  GM is stating that it does not support the sale of Saab to two Chinese auto companies.  Without financing, Saab is likely to be liquidated by the Swedish courts, a process that was suspended when Saab made a deal to sell itself.  

I have friends who own Saabs, and I wonder what will happen to them as far as vehicle service and replacement parts go.  Perhaps someone will step up and buy the parts inventory, if there is money to be made in service.  Some Saab models are really re-badged GM or Subaru vehicles, so those likely can be serviced at those dealerships.

EVs Are Expensive!

Ford today announced the pricing for the electric Focus, $40,000.  Facebook and blogs are howling at the price.

Truth is, the price is not unfair.  Li-Ion batteries are running around $600/kWh these days.  If the Focus matches the Leaf's 24kWh battery, then it is carrying about $14,000 in batteries.  A nicely equipped Focus goes for around $23,000, which gets us to $37,000.  

I suspect that Nissan is losing money on the Leaf, and calling it a marketing expense.  At a price of $32,000, the Leaf only allows for a base vehicle price of $18,000.

Review: Drop Stop Car Wedge

Drop Stop Car Wedge is a simple product that does one thing very well. It blocks the gap between your car seat and the center console, so that you can't drop stuff down into that hard to reach spot. 

I have been using one, and It works great. I do notice that I can feel the right side of my seat is button cushion is a little bit firmer due to compression, but it doesn't bother me.

The wedge is a tube made of black neoprene, with a pass-through for the seatbelt latch.  It is stuffed with filler.  To install it, you slip it over your seatbelt latch and then stuff it down, working it forward and back smooth it out. 

At $20/pair plus shipping, it isn't cheap, but isn't outrageously expensive either.  It should outlast your vehicle.

Pros:
  • Simple, effective
  • Unobtrusive
  • Seems durable
Cons:
  • Unknown country of origin (not on packaging)
  • $20+shipping is a little steep for what is basically a stuffed fabric tube
  • Limited distribution (Can't buy it on Amazon, etc.)
  • Adds firmness to right seat cushion side


*Note: DropStop did not provide any payment for this review, other than sending me a test unit.

Sonic Drop Breaks Down?

Chevy is doing a stunt to promote the new Sonic b-car.  They are dropping it off of a huge tower attached to a bungee cord, and using web clicks to move it towards the edge of the leap.

Looks like it broke, though.  

I hope those guys are careful.

Minor Fact Check: Volt Charging Handle

According to Mike Davis at The Detroit Bureau, the Chevy Volt charging cord has a safety feature similar to a certain .45ACP pistol that I know and love.

"To my surprise, I found the In cord had a squeeze-handle like the safety grip on a Model 1911 A1 .45 pistol"

Sorry Mike, this isn't right.  The 1911 has a grip safety on the backstrap of the gun, where the web of your thumb rests.  The Chevy Volt has a safety lever located under the trigger finger.


Electric Delorean?

Jalopnik's Kevin McCauley was invited to test drive a Delorean DMCEV, an electric conversion applied to a Delorean chassis by the new Delorean Motor Company.  DMC hopes to build these for sale in 2013.

It will be a really cool looking car, but remember that this thing is built on a 1980's design.  It wouldn't pass modern handling or crash standards.  And chances are, it will be really expensive--because to avoid meeting the modern standards, each one of these will have to be a conversion of an existing Delorean chassis with an existing VIN.  In other words, take a rare car, and then apply expensive electronics and batteries.

I have to say, though, the Delorean is still a great looking car.

Electric DeTomaso, Pantera, anyone?

Ford Quietly Kills Off Hybrid Escape?

Ford has announced that the next Escape, based on the European Kuga, will come with 3 flavors of I4 engines, 1.6L Ecoboost (GTDI), 2.0L Ecboost, and 2.5L NA.  No mention was made of the hybrid powertrain currently available, giving Ford bragging rights to "most fuel efficient SUV".  So it looks like Ford is quietly killing off the hybrid Escape in favor of the C-Max hybrid and plug-in hybrid.  

If I have this wrong, Ford PR is invited to comment.

SUVs Less Dangerous To Others*

A new study by the IIHS shows that SUVs which strike cars of a similar weight are now not more dangerous than other types of vehicles.  This is great news, as it shows that automakers have been taking the interface issue seriously.   By adjusting the heights of crash structures, moving towards unibody designs, and improving crumple on light SUVs, automakers have been able to meet or even exceed sedan crash performance.  

However.

The study looks at crashes where vehicles collide which are within 500lbs in weight of each other.  It does not say much about crashes where the vehicles are farther apart, for example a 5000lb SUV striking a 3500lb car.  In cases like those, injuries and deaths are still going to be lopsided, with the occupants of the lighter vehicle suffering more damage.  

This chart from IIHS is telling, it shows how heavier vehicles tend to have higher partner death rates than lighter ones.  

At the end of the day, a larger, heavier vehicle is still safer, for the people riding in it.  But not necessarily for the others on the road.

My Sad HP Tale

I decided to replace my stuttering old Dell Optiplex desktop (Core 2 circa 2008) with a new desktop.  I saw a very good deal on Woot!--an HP Pavilion with a quad core AMD CPU and 1TB HDD for all of $300.  It was, of course, refurbished.

That was a mistake.

The HP came loaded down with crapware (trials, useless media players, etc.).  The Pavilion case was made of very thin metal, and thing made a lof of an and drive noise compared to my old machine.  But the worse part was that it came broken.  Despite having 4 RAM slots, the motherboard would not boot if I put more than 2 sticks of memory in it.  HP agreed this was an issue, but informed me my machine was out of warranty.  After several long phone calls with customer service (in India) I finally got them to extend my warranty to the proper 90 days, and accept the machine for repair.

It came back with a new motherboard, and would accept more memory.  But this one would run for a seemingly random amount of time, and then freeze solid. It wouldn't even write the errors into the Windows system log, so I had no way of knowing what was wrong.

The machine went back to Woot for a refund, and I bought a factory refurbished Dell Optiplex 780, with Intel Core 2 Quad CPU.  

The Dell Optiplex came with no crapware, other than a a free trial for a virus scanner, which was easily removed.  The machine is quiet, and fast, and with a free web coupon, it was cheap too.  And, unlike the HP, the Dell came with a 3 year warranty, and an actual restore DVD.

The I3 Is The New I4?

Ford has unveiled a GTDI (gasoline turbocharged direct injection) 3 cylinder engine, which they brand Ecoboost.  The 1.0L inline 3 will power the Fiesta and Focus C-Max in Europe in 2012, and will be competitive in power to the 1.6L I4 Ford currently offers, according to Ford's PR.  That means HP and torque numbers around 100-120HP and 110-120 ft-lb of torque.   Due to reduced weight and the variable-displacement effect of turbo charging, fuel economy numbers will be big.

Getting 100+ HP out of 1.0L is impressive, and matches the power output of such high-end makers such as Audi, BMW, and Porsche.  

The only other automaker that I have heard was working on a 3-cylinder engine, potentially for North America, was BMW (Mini).

Ford hasn't announced North American plans for the 1.0L Ecoboost, but I expect it will show up here eventually in Fiesta and possibly as a base engine for the Focus.   People will have to get used to such a small engine, and only 3 cylinders, but thanks to CAFE, very small engines are the way of the future.
