GM claims it's first to sell million 30+ mpg vehicles

As we continue to put together all the data for the year-end edition of By The Numbers, General Motors has announced that it sold more than a million vehicles in the US last year that achieved at least 30 miles per gallon on the highway. More impressively, GM managed this feat using multiple strategies including small vehicle size, turbocharged engines and hybrid or plug-in technologies across four brands (Buick, Cadillac, Chevrolet and GMC) accounting for 13 separate models. This number will grow even more in 2013 thanks to cars like the all-electric Spark, the diesel Cruze, the range-extended Cadillac ELR and the Buick Encore compact CUV.
GM's small car sales were up 39 percent last year helping to attain this million-sales mark for 30-mpg models, and almost 40 percent of all GM sales consisted of cars with fuel-efficient I4 engines. In regards to more advanced means of improving fuel economy, GM says that it plans on having 500,000 vehicles with "some form of electrification" on the road by 2017.

Cadillac CT6 gets a plug in Shanghai, will come to US

Don't call it the third coming of the Chevy Volt. The unsurprising debut of the Cadillac CT6 PHEV in Shanghai today has a powertrain that sounds an awful lot like the one that can be found in the Volt and the Cadillac ELR. The plug-in CT6 – identical to the CT6 that debuted in New York earlier this month – has an 18.4-kWh lithium-ion battery (just like the 2016 Volt) and offers an all-electric range of around 37 miles. It also copies the "Regen on Demand" feature from the new Volt and the battery cells "use the latest generation cell chemistry found in other GM plug-in vehicles." But Cadillac President Johan de Nysschen doesn't see the two powertrains as similar in at least one important way. General Motors calls the Volt and the ELR "extended range electric vehicles" (EREV) but in a statement, de Nysschen says that the plug-in hybrid CT6 is, "an ideal platform for Cadillac to offer its first plug-in hybrid." That GM is using the PHEV terminology rather than EREV is going to be important to some, even if the practical difference is only semantic. And yes, we all understand the irony of de Nysschen – the same guy who has a history of speaking ill of plug-in cars – hyping them now. Back when he worked for Audi, he said the original Volt was too expensive for what it offered and was thus, a car for "idiots." Speaking in Shanghai today, de Nysschen said the new CT6 PHEV was, "an EV without any of the disadvantages or range constraints," according to Automotive News. If the batteries are similar to GM's other EREV/PHEV cars, the CT6 powertrain is at least different. The ELR uses a 1.4-liter engine, while the new Volt has a 1.5-liter four-cylinder mill. The CT6, on the other hand, has a 2.0-liter turbo four-cylinder engine with direct injection. There is also an "all-new rear wheel electric variable transmission (EVT) with exclusively designed motors," that will give the CT6 PHEV, "smooth, spirited acceleration." The EVT is a two-motor-unit that uses three planetary gears. Maximum overall system output is 335 horsepower and 432 pound-feet of torque. Perhaps most interesting for American audiences is the fact that GM's press release, available below, makes multiple references to US-market sales of the PHEV. Official details on the EV range and fuel economy will be made available closer to the car's US launch.
