Classic Pontiac Trans Am Firebird Super Duty 455 sells for nearly $90,000

Historically, the Pontiac Firebird Trans Am raised the performance levels a notch or two over a plain Firebird in the muscle car hierarchy of the Sixties. But the Super Duty 455 version of the Trans Am — that number represents the cubic inches of the hand-assembled V8 engine — moved the performance needle big time in 1974. So much so that a clean example of the machine sold recently on the Hagerty Marketplace auction site for $89,296. Advertised with just under 54,000 miles on the clock and having undergone a thorough restoration, the Buccaneer Red model was one of just 943 Pontiac Firebirds equipped with the Super Duty 455 package for the 1974 model year. That build had also been offered in 1973. The Hagerty listing drew more than 21,000 views and 39 bids. According to Hagerty's valuation report, a similar car would be worth $85,700 in good condition, and $103,000 if it was in ‘“concours condition.” The Super Duty motor borrowed technology from the lineÂ’s 366-cubic-inch NASCAR engine, and featured heavy-duty connecting rods and an entirely new block with a revised crankshaft and heads to deliver a claimed 310 horsepower. The Firebird that sold was indeed loaded, with a three-speed Hydra-matic transmission (which surely reduced its overall value), power locks and windows, AC, dual exhausts, heavy duty stabilizer bars all around, and a “custom Interior trimmed in Red perforated Morrokide vinyl upholstery.” The entry of PontiacÂ’s pony car in the U.S., facing off against the Mustang and Camaro, dates back to 1967, when it was offered with an inline six and optional V8. The first Trans Ams were introduced two years later, the name derived from a handling package. General Motors ceased production of new Pontiacs in 2002 owing to declining sales and losing stakes in the sports coupe market. The big 455-cid V-8 had disappeared years earlier.

700 horsepower Porsche GT2 RS is the wildest 911 ever

The Porsche 911 comes in a variety of flavors, each filling a certain taste for a certain customer. Sitting atop the range is the new 911 GT2 RS. In previous generations, the GT2 had a bit of a reputation as a widowmaker, a 911 with massive power that could snap and bite with the slightest agitation. Porsche says the new model has been civilized, but with 700 horsepower going to the rear wheels, we're sure it's going to be as mad as ever. Power comes from a highly massaged version of the 3.8-liter flat-six from the 911 Turbo S. The rear-mounted engine makes an outrageous 700 horsepower and 553 lb-ft of torque. Like we previously reported, the new car will use water injection to help keep things cool. The only transmission is Porsche's PDK. While enthusiasts may lament the loss of the manual, the RS models have always been about performance above all else. Simply put, the PDK is the better performance option. All that power translates to a 0-60 mph time of 2.7 seconds and a top speed of 211 mph. The engine makes 80 more horsepower than the previous model. That makes it the most powerful road-going 911 ever built. In fact, the 887 horsepower 918 Spyder is the only road-going Porsche that makes more power. The fact that Porsche trusts all of that power to go to the rear is both thrilling and terrifying at the same time. In order to manage traction, the GT2 RS gets a number of upgrades. Rear-wheel steering has become commonplace in the 911 lineup, so it's no surprise to see it here. Sticky tires with 265/35 ZR 20 section rubber at the front and 325/30 ZR 21 section rubber at the rear keep things planted. That comically large rear wing adds downforce, adding to stability. The car gets standard carbon ceramic brakes. While some people prefer traditional rotors for the street, like the PDK, this is all about performance. A number of intakes and outlets complement the rear wing and maximize aerodynamic efficiency. It's a bit of a surprise that with all the focus on downforce, the GT2 RS still manages to top out at 211 mph. The hood, front wings, wheel housing vents, door mirrors, side air intakes, parts of the rear end, and a number of interior components are all made from carbon fiber. The roof has been made of magnesium. If you want to drop any pretense of civility and comfort in the pursuit of speed, Porsche is offering a Weissach package that shaves off another 40 pounds from the already impressive wet weight of 3,241.

Junkyard Gem: 2001 Pontiac Bonneville SSEi

The General's Pontiac Division sold Bonnevilles from 1958 through 2005, which turned out to be well over half of the marque's existence. Named after the Bonneville Salt Flats, some Bonnevilles were huge but pretty quick, others were slow-motion land yachts, and some were nearly indistinguishable from their Buick and Oldsmobile brethren. The final generation, sold for the 2000 through 2005 model years, were among the quickest and most distinctive-looking Bonnevilles ever built, but they arrived in showrooms at a time when the clock was ticking for the division's very survival. Today's Junkyard Gem is one of those cars, an '01 with the hot-rod SSEi package. The Bonneville SSEi first appeared in the 1992 model year, just a year after the Buick Park Avenue Ultra was the first of many GM cars to get the 3.8-liter Buick V6 with an Eaton supercharger bolted on top. Production of the Bonneville SSEi continued through the 2003 model year, after which the GXP version and its Cadillac Northstar V8 took over. The 2001 version of this engine made 240 horsepower, good for plenty of torque-steery fun. Could you get this car with a manual transmission? What do you think? Some cursory research indicates that 1970 was the last model year for a three-pedal Bonneville, and even those cars must be incredibly rare. This one looks to have been in nice shape when it arrived here, with the original manuals still in the glovebox. By 2006, the Bonneville was gone; four years later, Pontiac was gone.
