“Nobody Expects Volvo to Sell Many”

The title of this post comes from a quote on Plugincars.com.

The analyst says no one expects Volvo to sell many plug-in electric-diesel hybrid cars despite a 117mpg rating (I’ve read claims of 149mpg elsewhere) and 30 mile range on the electric motor. The US$70K might be the problem, but the site also points out it’s less expensive than a Lexus. And the Lexus engineers only offer 40mpg with their hybrid!

T3 offers the following conclusion:

The V60 is every bit the luxury car and despite government grants beyond most budgets, but with exceptional energy savings, zero road tax, congestion charge and reduced fuel costs it should be a no-brainer for company car drivers who want power and their bosses who crave efficiency.

An all-wheel-drive, plug-in electric-diesel hybrid full-size luxury car that goes 0-60 in 6 seconds yet stays over 100mpg? Are you kidding me? I’ll take ten.

Dear Volvo, I would buy one and I know many others who would too…just tell me, what will it take for us to get it in America?

New Diesel Taxi for London, NYC, and Tokyo

London makes it very clear that they have chosen a 1.5 dCi EuroV diesel engine with a 6-speed manual as their new taxi standard. Tokyo and NYC are said to be getting the same Nissan NV200 taxi in a new 10 year contract.

Although it is a fairly large size van that can carry five adult passengers and significant load, it is expected to average 53.3 mpg. Clean air is a major marketing point in London’s campaign.

The New York site, however, doesn’t say anything about the engine. Will the NV200 in the Big Apple also get cutting-edge diesel technology? Strangely, there is no mention of a mpg number in any of the U.S. press.

Even worse, the “Taxitistics graphic” for NYC makes no mention of air quality or engine efficiency at all!

Note the black cloud imagery. Thus I suspect the vehicles in different cities will actually be very different. Unlike the high-tech London taxis, NYC passengers should expect to be dragged around by a dated and anemic gas engine that takes more pit-stops because it gets no better than 25 mpg. If it is the same 2.0L 4-cylinder gas engine as in Nissan’s Sentra, then the match-up would look like this:

City London NYC
Engine 1.5L diesel EuroV 2.0L gas PZEV
Torque 216 142
mpg 53.3 25

More power, more efficiency…Londoners will get to their destination at less cost and more quickly and cleanly, because they chose a diesel fleet. For reference, the torque of Nissan’s new diesel is comparable to a Dodge Power Wagon.


A quick calculation:
13,237 taxis traveling 70,000 miles a year is 926,590,000 total miles per year.
At 25 mpg that would be 37,063,600 gallons.
At 53.3 mpg that would be 17,384,428 gallons (19,679,172 gallons saved)

At $4/gallon (current price of both gasoline and diesel in NYC is $3.9/gal) the savings from diesel engines in NYC would be $78,716,688 a year ($0.30 per passenger trip).

In other words, all else being equal, it will cost NYC $6,000/year more per taxi to run gasoline instead of diesel.

In just five years the NYC taxi will spend $30,000 more to operate than a London taxi, yet depreciate in value faster.

Likewise, waiting until electric engines are available (estimated in 2017 for NYC) would waste 78,716,688 gallons of gasoline at a loss of $314,866,752 ($0.40 per passenger trip).

That’s before calculating the emission harm differences. Again, NYC has said nothing about clean air. Taxis with diesel engines also are able to drive further without stopping to refuel, saving significant time and making them more available.

USCG Arctic Shield Operation

After the end of WWII hostilities the U.S. Navy deployed “task forces” all over the world. From the South Pole to the North Pole there were military teams mapping territory, assessing risk and seeking out remnants of opposition.

At least a dozen ships with double that many aircraft were assigned to study “techniques” for operation in extreme conditions and remote locations, as well as gather information the military considered “interesting”. Whether fueled by fear, suspicion or curiosity, the missions and their findings kicked off a huge body of knowledge about survival and risk management.

One way to get a sense of the number and types of teams is to look at photographs from aviation archives. Here’s a 1947 photo from LogBookMag of a Navy Douglas R4D-5 Skytrain (AirForce C47A) launching from an air craft carrier in Operation Highjump. Note the snow skis and the use of jet-assistance (JATO bottles).

R4D-5 Skytrain Launches

JATO was effective not only for small carrier runways but apparently also came in handy after skis froze to the ground.

By 1951 some believed that the U.S. was at risk of attack by the U.S.S.R. from the north. The CIA Factbook map makes it pretty obvious why; the distance straight over the pole is far shorter than following a latitude.

North Pole

The threat of increased traffic warranted understanding the region, establishing forward bases and learning to operate there. The American military stepped up research on extreme temperature survival, early-warning systems and rapid-response above the Arctic Circle.

Innovations like the “flying laboratory” were developed and used in Project Skijump, although it had a landing-gear failure in 1952 and was lost to the Soviets.

Fast forward to today. The U.S. Coast Guard has announced a massive expansion of operations above the Arctic Circle and a forward base at the northernmost city in America. The Fairbanks Daily News gives their perspective on the need for assistance.

Barrow is surrounded by open tundra and the Arctic Ocean. As sea ice continues to disappear, the city will begin to experience increasing boat traffic, both from companies planning to drill for oil and travelers looking for a shortcut from the Atlantic to the Pacific.

That is why the Coast Guard sent an aviation team more than 900 miles from its home in Kodiak to Barrow: It needs to be prepared if something goes wrong.

I wonder how much of the preparation from the past is useful for future incidents. The NYT makes it sound like the USCG is starting from scratch.

“The Arctic has been identified as a priority,” said Cmdr. Frank McConnell, the operations coordinator for Arctic Shield, which includes in its initial phase two Coast Guard cutters and two smaller ships, in addition to the two helicopters that will be stationed here in Barrow. The first of 25 pilots, along with support crews, mechanics and communications personnel, began rotating through Barrow this month on three-week tours. “There’s a lot to learn,” Commander McConnell said.

That’s what they said in 1947.
