1938 and 1939 Auto Union Type D Grand Prix Racers.
This summer, Audi filled a gaping hole in their historical collection when they acquired a twin-supercharged V-12 powered 1939 Type D grand prix car that represented the pinnacle of Auto Union performance before the war.
Long in private hands and the recipient of technical assistance from Audi during its 1990s restoration, the mid-engined Type D will now sit in its rightful place in the Audi museum in Ingolstadt.

When World War II started on September 1, 1939, Auto Union and Mercedes-Benz were the class of the European Grand Prix racing circuit. Although the great Tazio Nuvolari managed to squeeze out a few improbable wins for the Scuderia Ferrari Alfa Romeo team in the mid-1930s, the Germans, whose cars were dubbed the Silver Arrows, absolutely dominated the scene. The last race of the era actually occurred on September 3, 1939, two days after Germany had already invaded Poland, when a 46-year-old Nuvolari won the Belgrade Grand Prix in an Auto Union Type D. The power and speed of the Silver Arrows would not be topped in grand prix racing until the turbo era dawned decades later.
While Mercedes-Benz was able to squirrel away their famous racing machines as Stuttgart fell into the Allied occupation zone, Auto Union was not so lucky as their headquarters in Zwickau fell under Soviet Control. The Soviets found the Auto Union racers, which had been safely tucked away in a mine building above ground, and seized them as war reparations and they vanished into the vast, well, vastness of the closed, communist state.

With rumors of the car's existence and whereabouts at a low static buzz in the 1970s, a Serbian-born American of Russian heritage, Paul Karassik, began his search for the cars. It took 10 years and he found just basket cases missing their bodywork, but Karassik managed to rescue enough parts to build two cars, one of which was restored as the twin-supercharged 1939 Type D and the other restored as a single-supercharged 1938 Type D.
The grand prix formula in the late 1930s specified a maximum 3.0 liters of engine displacement with supercharging or 4.5 liters without. The formula also called for a sliding weight scale from 400kg to 850kg. Top speeds with the right gearing were in the 200 MPH range and streamlined, modified versions of both Auto Union and Mercedes-Benz grand prix racers were built for speed record drives. Though neither company ever set the outright land speed record, they leapfrogged each other repeatedly, sometimes on the same day on the same course.

The 485-hp, 3.0-liter V-12 engine featured an exhaust camshaft on each bank of cylinders and a single, central cam in the vee for the intake valve operation as well as four carburetors. While Mercedes-Benz was clearly the class of 1939, with Herman Lang winning five of eight events and his teammate Rudolf Caracciola another, Auto Union did win two races: Nuvolari's victory in Belgrade and H.P. Muller's triumph at the French Grand Prix.
This car drew a fair bit of controversy a few years back when Christie's pulled it from a major auction, at a time when it was believed it could set a record for any car sold at auction. The controversy was that the car was at first presented as the actual car driven by Muller to win the French Grand Prix, but further research indicated that the serial numbers didn't match up. Auto Union ran 11 D-types during the 1939 season and the cars were frequently stripped down and rebuilt after each race, the parts from one machine possibly cross-pollinating to another, so saying any one car was definitively driven at a certain event is next to impossible. On top of that confusion, the parts Karassik recovered from the Soviet Union were from multiple cars and it was decided, after the parts were collected and inventoried, to build the two cars. The current consensus is that the car purchased by Audi is chassis number 19 and was driven by Hans Stuck to a sixth place finish at the 1939 French Grand Prix.

Specialty Vehicle Engineering
Specialty Vehicle Engineering (SVE) has done it again with its latest power-adding limited-edition build, this time for the 2024 Chevrolet Corvette. The latest Yenko/SC sports car received some serious upgrades for the sizeable boost in performance that Yenko-badged vehicles are known for.
The Yenko 2024 Chevrolet Corvette is powered by a twin-turbocharged 6.2-liter LT2 V8 engine capable of 1,000 horsepower, around double the power of a stock Corvette. Depending on the 2024 Corvette’s trim level, the factory power ratings run between 490 to 670 horsepower.
Releasing 1,000 horses out of the stable was made possible by the addition of two 58-millimeter water-cooled turbochargers, but before the turbos were tacked on, the V8 engine received some upgrades of its own. An ARP high-strength head, a forged steel crankshaft, forged H-beam rods, forged aluminum pistons, and a proprietary camshaft strengthen the internals, while a custom intake manifold, CNC ported high-flow cylinder heads, an upgraded fuel system, and a custom tune further opens up the L2 to all the added power. SVE couldn’t stop there: The Corvette’s eight-speed dual-clutch gearbox was also upgraded to withstand the extra power and blast it to the rear wheels.
SVE tops off the upgraded powertrain with custom valve covers. In the rear, distinctive exhaust tips are added and are available in silver or black. Yenko-badged brake calipers can be had in select colors, with the standard option being red. Three different designs of staggered 19-inch front and 20-inch rear wheels are also available in various finishes. Inside of the new Yenko Corvette are embroidered logos on the headrests and floormats, characteristic of the company’s other Yenko offerings.
SVE is offering its Yenko Corvette in coupe or convertible body styles, with any of the currently available factory Corvette color choices. Nine colors are available for the SYC graphics, plus the addition of a tenth carbon fiber option.
SVE confirms it will build just 10 Yenko/SC Corvettes for the 2024 model year, but that production number will increase to 50 for 2025. The Yenko/SC Corvette package starts at $99,995, not including the initial cost of purchasing a new Corvette.

We can’t help surfing online classifieds to search for deals and then getting caught up in daydream builds each time we come upon something interesting—that’s standard behavior for gearhead car enthusiasts. For those of us on staff here at Hemmings, having collector car classifieds and an online auction site under the same virtual roof just encourages those tendencies. So, when the end-of-month report of sold vehicles hits the inboxes around here, there are always some completed sales that jump out and make some of us wish we’d gotten in on the bidding action.
Every so often we'll hear from someone who thinks the Hemmings Marketplace only caters to high-end collector cars, and the players with the budgets to navigate in that realm, that really isn’t the case—there are always deals to be had among the offerings, some that really stand out. If fact, when the roundup of April sales came out recently, I noticed several vehicles that made me think I should have been paying more attention while bidding was still going on. Here are a few highlights that really got the wheels spinning in my head with some theoretical projects.
1974 GMC Sierra Grande
<p>This truck was the vehicle responsible for making me delve deeper into the April sales listings to see what else I had missed. The weathered “Bright Green Iridescent” paint grabbed me and set the tone for a rig that looks like a ‘70s drag racer’s dream hauler from the days when dually pickups were something new and “3+3” crew cabs were still somewhat unusual. That “double-decker” bed topper, paint matched of course, with its Vista Cruiser-style windows (or were they inspired by that ‘70s big-rig icon, the Kenworth Aerodyne?) lends hard to the old-school drag race hauler vibe this thing is putting out hard. More nuanced evidence lies with the high-trim Sierra Grande package and the Camper Special equipment, ordered for a truck that was going to do some travelling, but not with a camper</p><p>Naturally, this one has a 454 and a TH400 automatic, and the listing detailed that the current engine was a replacement, though the original would also be included. For gearheads, that’s a nice bonus, as an early ‘70s 454 core is always good to have around. However, once the daydreaming got underway, a few of us in the office began to envision this hauler with a transplanted 8.1-liter Chevy big-block from the early 2000s backed with an Allison five-speed automatic—both of which could be plucked from a rusted and retired work truck one of our friends currently has. That relatively low-buck swap would make this thing a killer retro-styled tow rig for interstate travel. The bonus would be having not one, but two 454s to play with for hot rod projects. </p><p>That bright green paint was a bold choice even amid the flash of the ‘70s, and with a truck this large it screams of the period in a very cool way. The years of seasoning that left the aforementioned “patina” finish will make it all the more appealing to today’s classic truck fans. </p><p>That sort of western sunbaked finish is often accompanied by a similarly baked interior, but not here. The seller makes mention of reupholstery work done about a dozen years ago, and though the listing describes sun fading and cracking on parts of the seat covers, it also said there were no cracks in the dash pad, and the door panels looked to be in good shape too. </p><p>We couldn’t believe this unit went for just $5,600, and several of us were kicking ourselves for not bidding. Man, this thing is cool. </p><p><a href="https://www.hemmings.com/auction/1974-gmc-sierra-grande-huntsville-al-224267/sold" target="_blank" rel="noopener noreferrer">https://www.hemmings.com/auction/1974-gmc-sierra-grande-huntsville-al-224267/sold</a></p>
1964 Dodge 880
<p>Back in 1964, this Dodge 880 four-door sedan would have seemed like a run-of-the-mill car, blending in with the scores of other sedans on the road and looking mostly contemporary, though maybe a touch dated. But today, despite it being a body style that has traditionally been eschewed by enthusiasts, this Dodge would certainly turn heads. It’s not even a hardtop, yet this Dodge’s period style and excellent condition ought to allow it to get a pass even from enthusiasts who might normally dismiss it as a “more door.”</p><p>There wasn’t a lot of background given in the description, but looking over the photos, you can see that the back seat still wears a vintage clear-plastic seat cover, likely installed when the Dodge was new and almost certainly responsible for the outstanding condition of the upholstery up front, where we’ll guess another more deteriorated clear cover was recently removed. The pushbutton automatic and dash-mounted rearview mirror were the norm for Chrysler Corp cars at that time, but both are oddities that now add to this Dodge’s quirk factor. The 361-cu.in. V-8 has a displacement that probably sounds unfamiliar to many enthusiasts, but it was a member of Chrysler’s B-series of low-deck, “big-block” V-8 engines, along with the widely recognized 383. And if the accompanying video clip is accurate, this 361 runs like a Swiss watch. </p><p>Overall, most of the mechanical parts on this Dodge ought to be sourced somewhat easily, from that engine to the TorqueFlite transmission, the 8-3/4 rear axle, and many of the chassis parts, since this model was built on the Chrysler C-body platform. All of this should make it a great classic to use as a regular driver, and for the sale price, it would be hard to go wrong. </p><p><a href="https://www.hemmings.com/listing/1964-dodge-880-447036/sold" target="_blank" rel="noopener noreferrer">https://www.hemmings.com/listing/1964-dodge-880-447036/sold</a></p>
1971 Alfa Romeo Spider
<p>If you’ve ever owned, or even just looked into owning, a vintage Alfa Romeo, you know what a deal this sale was. The 1971 Alfa Spider was among the earliest of the “square-tail” body style that lasted up into the early ‘80s, though of these, the earliest cars are the most prized for their slender bumpers with stainless steel trim. For North American Spiders, the ’75-on models had large, rubber-clad bumpers to cope with 5-mph laws, along with a steadily expanding array of smog-coping alterations. This particular Spider was partially dismantled and offered as a project vehicle, but even at that, it was a bargain. </p><p>All Alfas of this period were highly susceptible to corrosion, and it’s pretty standard to see rotten rocker panels, missing spare tire wells, and ventilated floorpans, but this one seems to have avoided the usual deterioration. The seller claimed the car had spent much of its life in Arizona, and that’s what it would take for one of these to avoid oxidation as well as this one seems to have managed. The baked paint and crumbled seat upholstery and foam support the notion that the Spider spent its time in the desert. This very early square-tail also had the desirable 1750-cc version of Alfa’s classic twin-cam four-cylinder; the 2,000-cc version replaced the 1750 shortly after, but many members of the “Alfisti” will say the 1750 is the favored configuration, seeming "snappier" and more willing to rev. </p><p>The engine and transmission were present, as was the North American-spec SPICA mechanical fuel-injection. Most Alfa enthusiasts prefer side-draft carburetors, as Alfa intended (the carbs wouldn’t pass American emissions regs), but the SPICA system is robust and reliable when functioning—hopefully this one hasn’t suffered too badly from decades of storage. </p><p>The listing said the seat frames and top frame were also present, though it offers no mention of some of the smaller trim, like those coveted slim bumpers. This car even came with a clean title and some other factory documents. Though there is clearly plenty of work ahead to put this Spider back on the road, the buy-in for this project would make it easy for someone to invest some more—haggard parts cars for this model usually cost more. Someone scored here. </p><p><a href="https://www.hemmings.com/auction/1971-alfa-romeo-1750-berthoud-co-985603/sold" target="_blank" rel="noopener noreferrer">https://www.hemmings.com/auction/1971-alfa-romeo-1750-berthoud-co-985603/sold</a></p>
1955 Ford Fairlane
<p>Okay, another four-door sedan here, and one that would have once been among the most commonly seen cars on the road. But that time was nearly 70 years ago; today, this Ford would stand out in any automotive gathering. Helping it garner attention is that very period turquoise and white two-tone paint, trimmed with thick, bright-metal moldings, looking almost like a caricature of a 1950s American car.</p><p>The listing says this Ford has the 292-cu.in. version of the Y-block V-8 and an automatic transmission, so it ought to be fairly easy to drive and capable of hanging with modern traffic in most situations. However, very little was offered in the listing, other than to say that the car has been off the road since 2000 and will need its fuel tank installed in order to run. That tank is said to be new, so perhaps a rusted original tank contributed to the Ford being set up for a time. </p><p>The few interior photos show what appears to be nice upholstery, with a textured pattern that also screams ‘50s in an appealing way. No alterations from stock are evident in the limited view inside. Meanwhile, under the hood looks more like a typical workaday car or truck—dirty and with very aged paint, but in a way that appears functional and un-messed with. If it runs, the new owner can tackle the engine-bay sprucing as a relatively simple renovation project. </p><p>For anyone wanting a ‘50s car to cruise for low-commitment fun, this Ford would provide an excellent entry point. For the selling price, some further investment could still be made that might feasibly be recouped later if the car was sold in running, driving condition. Well bought here. </p><p><a href="https://www.hemmings.com/listing/1955-ford-country-sedan-407091/sold" target="_blank" rel="noopener noreferrer">https://www.hemmings.com/listing/1955-ford-country-sedan-407091/sold</a></p>
