Volkswagen 1.5-liter TSI engine

Diesel? What’s that?

Volkswagen is embracing a far less controversial type of fuel with its new 1.5-liter TSI engine, unveiled yesterday at the Vienna Motor Symposium.

The ultra-efficient four-cylinder uses variable turbine geometry (VTG) in its turbocharger to generate peak torque at a low 1,300 rpm, then maintain a flat torque curve until about 4,500 rpm. This leads to fuel economy gains and a better driving experience. Read More >

Update: I made a decimal flub. The math is corrected. Thanks to commenter ChemEng for pointing it out. We’ll post a new piece on Monday.

There’s no denying it: Volkswagen cheated. It confessed to the crime of emitting up to 40 times over the legal limit allowed for NOx. We learned yesterday (and the day before, to some degree), that Volkswagen will fix the vehicles that can be fixed, if owners so choose.

But what happens to all those diesel cars, which are perfectly good aside from emitting more NOx than they should, if owners decide to cut and run? And what happens to all those vehicles that can’t be fixed? Volkswagen has vowed to buy them back from customers — to which I ask, what then?

There are few options Volkswagen can employ to unload the massive windfall of cars coming its way, and none of them are particularly environmentally friendly.

2015 Volkswagen Jetta TDI (1 of 8)

Note: In light of today’s news regarding an agreement between Volkswagen and U.S. regulators, we believe it’s pertinent to rerun this piece considering Volkswagen still plans on fixing some of the affected 2.0-liter TDI vehicles. —MS

In all reality, Volkswagen probably won’t pay $37,500 for each car that cheated its way through U.S. emissions standards, but the German automaker will probably pay thousands for each car to fit a device that would clean up their acts.

The presumed fix would come by retrofitting a Selective Catalytic Reduction (Adblue or urea) system although that wouldn’t be the only fix necessary. Researchers discovered that the Passat TDI that they tested, fitted with the SCR system, was 5 to 20 times over the NO limit — less than the 10 to 40 times by the lean NO filter cars, but still illegal.

The long list of items needed to fit models of the Volkswagen Golf, Jetta, Beetle and Audi A3 doesn’t include the engineering needed to retrofit the cars and the costs to crash test the models after the significant modifications. That’ll add hundreds of millions to the bottom line.

Chevy_Volt_EPA_Fuel_Economy_Official_Label

As regulatory bigwigs gear up for a midterm review of corporate average fuel economy (CAFE) requirements, will the 54.5 mpg target for light-duty vehicles get a haircut, or be deemed too  unambitious?

Under a 2012 agreement between the federal government and automakers, cars and light trucks will have until 2025 to meet the 54.5 mpg target, which works out to about 40 mpg on the window sticker (for cars) after you ditch the fancy math. That target isn’t set in stone, and the midterm review will take into account the state of the market — and existing technology — when it reviews its goals for the 2022-2025 period. Read More >

2017 Mitsubishi Outlander PHEV

Mitsubishi has a plan to gain market share in the U.S. that’s right out of the ’80s.

Dealers were told during last weekend’s National Automobile Dealers Association conference that Mitsubishi will introduce turbocharged engines to model line, according to Automotive News.

The forced-induction renaissance will begin with a 1.5-liter mill powering the automaker’s planned midsize crossover, expected in 2018, which will slot between an enlarged Outlander and the Outlander Sport.

Volvo S60 V60 Polestars

Volvo set a corporate high-water mark for speed today by launching two new Polestar models, each with enough power to make a tenured Vermont professor blush.

Dropping two cylinders while gaining 22 horsepower, the upgraded S60 and V60 Polestars are part of Volvo’s effort to boost the visibility of its performance division.

The 2.0-liter Drive-E four-cylinder in the S60 and V60 Polestar (replacing the previous blown straight six) was worked over by Polestar engineers to make 367 horsepower and 347 pounds-feet of torque. The mill, which makes 240 horsepower in T5 models, gains muscle from a supercharger, larger turbocharger and air intake, and a higher-capacity fuel pump.

tdi_fix

It looks like Volkswagen has inadvertently sent a fix for its illegally polluting TDI vehicles to a customer, along with a letter spelling out the costs of said fix.

The fix, which is included on an OBD II adapter, wasn’t supposed to be sent with the letter, explained the TDI owner who wished to remain anonymous. Other TDI owners can expect to receive their fix in the next 90 days, says the letter.

“Hybrids? Those things that can’t make up their mind on what they want to be in life? Come on!” – Mazda.

That, Volkswagen floors the accelerator past a deadline, March looks like a boffo month for vehicle sales, Audi dials it back a bit, and getting a Tesla Model 3 depends on whether or not you’re in the club … after the break!

2016 BMW i8 Hybrid Exterior-006

BMW Group is laying out its game plan for the future, and it includes a lot of new electric vehicles.

Beyond the marketing buzzwords, there’s much similarity between BMW’s plan, released yesterday, and those of so many other automakers: building high-tech convenience and connectivity into their vehicles, diversifying their electric offerings, developing autonomous driving technology, and making the customer feel extra special.

The immediate effect on BMW’s rolling stock will be an expanded “i” range of all-electric or plug-in hybrid models, starting with a convertible version of the i8 and a longer-ranged version of the i3 by the end of this year.

A former employee, who was fired after news of Volkswagen’s diesel emissions scandal broke, is claiming in a lawsuit that he was let go from the automaker after noticing data related to the scandal was being deleted, several German language outlets are reporting (via Automotive News).

The lawsuit, filed by a former employee of Volkswagen Group of America, is the first possible evidence made public so far of a good, old fashioned cover up on this side of the Atlantic.
