Junkyard Gem: 1981 Cadillac Eldorado with V8-6-4 engine

Skyrocketing fuel prices caused by geopolitical events in 1973 and 1979 led to gas lines, federal fuel economy requirements, and an increasing reluctance on the part of American car shoppers to buy big, thirsty Detroit luxury machines. General Motors had pulled off some amazing technological feats in the past — the small-block Chevrolet V8 engine and Hydramatic transmission being two extraordinarily successful ones — and so Cadillac's bosses figured that a combination of computer wizardry and clever mechanical engineering would give the 368-cubic-inch Cadillac V8 a cylinder-deactivation system and resulting superior fuel economy. Here's a very rare example of one of those 1981 Cadillacs, found in a California self-service wrecking yard. The idea behind the V8-6-4 was that computer-controlled solenoids would physically disengage the rocker arms for one or two cylinders on each engine bank under low-load conditions, converting the engine from a 368-cube V8 to a 276ci V6 or 184ci V4 (that's 6.0, 4.5 or 3.0 liters, respectively, for the metric-system aficionados among us). This sort of variable-displacement magic is commonplace today, but it was science-fiction stuff in 1981. An "MPG Sentinel" display on the dash would let the driver know how many cylinders were active at the moment, and the car would get Chevy Citation fuel economy with Cadillac luxury. The V8-6-4 was the standard engine in all 1981 Cadillacs (except for the Seville, which had the troubled Oldsmobile diesel engine as the base powerplant and the V8-6-4 as an option). Unfortunately, the V8-6-4 worked about as well as the Oldsmobile diesel: very poorly. Within a few years, most owners of these engines had disconnected the rocker-deactivation solenoids and just drove their cars as regular full-time V8s. This one has the snazzy "Cabriolet Roof Treatment" option, which boasted "textured elk grain" vinyl and could be had in one of 17 available colors. Front-wheel drive gave the early-1980s Eldorado plenty of interior space, despite its more proletarian Olds Toronado origins, and these velour-covered seats made for very comfortable road trips. The price tag started at $17,550, or about $51,650 in 2019 dollars. The 1981 Imperial went for $18,311, and that car was based on the same platform as the lowly Plymouth Volare. Meanwhile, A BMW 733i cost $28,945 and a new Toyota Cressida a mere $11,599. The 1981 Cadillacs were just a little too much ahead of their time, it turned out.

GM's labor deal with UAW union on verge of ratification

Nov 15 (Reuters) - General Motors' tentative labor deal with the United Auto Workers (UAW) union closed in on ratification as the votes were counted on Wednesday. Following the approval earlier in the day by more than 60% of union members at the Detroit automaker's large Arlington, Texas, assembly plant, additional votes in favor have the deal close to clinching majority approval. The number of union locals, most of which are smaller, still to report vote totals is not large. After several large assembly plants voted against the deal earlier on Wednesday, some media had reported the deal was heading toward failure. But Arlington's support, followed by strong voting in favor by smaller warehouse and parts facilities, has put the deal on the brink of approval. This would mark the first ratification of a deal, which runs through April 2028, with one of the Detroit Three automakers. Ford and Stellantis voting is still under way, and workers at both companies were favoring ratification by comfortable margins. The UAW's GM vote tracking site currently shows approval of the contract leading by a 54% to 46% margin with almost 32,000 workers having cast votes out of about 46,000 UAW-represented GM workers. The Arlington plant, with about 5,000 UAW members, has the most of any GM plant. Voting officially ends on Thursday at 4 p.m. EST, although most votes will be cast on Wednesday. The UAW went on strike for more than six weeks against the Detroit Three, seeking better wages, working conditions and cost-of-living adjustments. All three companies agreed to tentative agreements about two weeks ago. Workers at other GM assembly plants voted against the deal, including 60% of workers at its Fort Wayne, Indiana, truck plant, 53% at its Wentzville, Missouri, plant, 58% of workers at GM's Lansing Grand River plant and 61% of workers at the Lansing Delta Township plant. Seven of GM's 11 assembly plants rejected the deal. In addition to Arlington, workers at plants in Detroit, Fairfax, Kansas; and Lake Orion, Michigan; approved the agreement. Only nine facilities are still listed without vote totals on the UAW vote tracker, including GM's Lockport, New York, components plant with about 1,200 members. Those voting in favor of the agreement have a lead of almost 2,500 and many of the facilities still to come include workers who stand to receive large pay increases upon ratification.

Cadillac CTS Vsport laps the N"urburgring in 8:14.10 [w/video]

You don't have to be German to test your car at the Nürburging. You just have to be serious about beating the Germans on their own home turf. That's why Nissan tests its GT-R at the Nordschleife to challenge the Porsche 911, and why Cadillac - which is no less serious about putting up a fight to German performance sedans - has returned to the 'Ring once again with its latest.
This time it's the turn of the new CTS Vsport, the sportier version of Cadillac's new mid-range sedan that aims to bridge the gap until the arrival of the next CTS-V. So how'd it fare? At the end of what we're sure was an exhaustive test session, the new CTS Vsport clocked a time of 8:14.10.
To put that into context, General Motors points out that the time places the new sedan six seconds ahead of the first-gen CTS-V, whose 400-horsepower V8 engine was actually less potent than the Vsport's new 410hp 3.6-liter twin-turbo V6. That's still a good fifteen seconds slower than the outgoing CTS-V that clocked a 7:59 in 2009 with its 556hp supercharged V8, but only a second behind the E60-generation BMW M5 with its high-revving 500hp V10.
