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.

Here's your chance to own a 7.0-liter V8-powered, stick-shifted Cadillac Catera

Cadillac never stuffed a V8 engine into the Catera, the entry-level model it sold in the United States from 1997 to 2001, so American tuner Lingenfelter stepped in and offered to perform the conversion. One of the few cars it dropped an eight-cylinder into is for sale, and the bigger engine is just one of many modifications performed on it. Listed on auction site Bring a Trailer, this 2001 Catera lost its V6 soon after it was leased to its first owner in Warren, Michigan. Lingenfelter replaced the 3.0-liter V6 with a 5.7-liter V8 and ditched the automatic transmission in favor of a six-speed manual, but that wasn't enough; the owner sent it back for more. It left the shop again with a custom-built, 7.0-liter V8 between its fenders. It's essentially a Chevrolet Corvette C5.R-based block topped with LS6 heads, an LS6 intake, and a less restrictive exhaust. Its horsepower and torque outputs aren't available, unfortunately, but we assume the V8 easily doubles the stock Catera's 200-horse output. Cadillac marketed the Opel-built Catera as the Caddy that zigs, not as the Caddy that humiliates hot rods on a drag strip, so additional modifications were required to keep the V8's power in check. Highlights include a limited-slip differential, a lowered suspension with bigger sway bars, and beefier brakes all around. At one point in its life, this Catera also received 17-inch alloy wheels, a three-spoke steering wheel, and a sprinkling of V emblems. Although engine swaps are often hit or miss, this Catera has spent approximately 18 years and 40,000 miles with a V8 under its hood, so it's apparently a solid, well-thought-out build. It currently has 42,000 miles on its odometer, and it's located in Michigan. Bidding stands at $6,250 as of this writing, with five days left in the auction. It won't stay in the four-digit range for long, and it might end up costing as much as a late-model ATS-V, but when are you going to find another one like it?
