Ferrari 275 S

Ferrari 275 S was a sports racing car produced by Ferrari in 1950. It was the first Ferrari powered by a new Aurelio Lampredi-designed V12 engine, created as a large displacement alternative to the initial 1,5 L Colombo V12, used in supercharged form in Ferrari 125 F1. Formula One regulations allowed for up to 4.5 L in naturally aspirated form.

Development

Only two examples were ever created. Both had Touring barchetta bodywork. Aurelio Lampredi designed new V12 engine that was intended for Formula One race cars, but first had to be tested in a sports racing car. This new 'long-block' displaced 3,322.34 cc (3.3 L; 202.7 cu in), thanks to 72 by 68 mm (2.8 by 2.7 in) of bore and stroke and had SOHC configuration with two valves and single spark plug per cylinder . Initially power output was 270 PS (199 kW; 266 hp) at 7200 rpm with 8:1 compression ratio. Engine was fed by three Weber 40DCF carburettors and used wet sump lubrication. Top speed was 240 km/h.[1]

Racing

1950 edition of Mille Miglia race was attended by both examples of 275 S.[2] Alberto Ascari with Senesio Nicolini drove 0030MT and Luigi Villoresi with Pasquale Cassani raced in 0032MT. Unfortunatelly both teams encountered transmission problems, that could not cope with high amounts of power, and did not finish the race. Cars raced only a couple more times in its 275 S guise.[3] Despite poor initial results the engine proved its potential and was immediately used for a single-seater Ferrari 275 F1, as was its original purpose.[4]

Specifications

Chassis was a ladder frame aided by steel tubes of a short, 2,250 mm (88.6 in), wheelbase, derived from 166 MM.[5] This value will change when upgraded to 340 America specification. Front suspension was independent and rear had a live axle with semi-elliptic springs. Stopping was by four-wheel drum brakes.[6]

275 S/340 America

Between 1950-1951 both cars were upgraded with new 4.1 L, also Lampredi, engines, that in turn were derived from Formula One powerplants. After conversion power dropped to 220 PS (162 kW; 217 hp). Now converted into 340 America model-line, one car s/n 0030MT was further rebodied by a new coachbuilder, Scaglietti, after 1952. The other car remained in Touring barchetta form.[7] S/n 0030MT was auctioned in 2015 by RM Sotheby's in Monterey for almost $8 million.[8]

Alberto Ascari

Alberto Ascari (Italian pronunciation: [alˈbɛrto ˈaskari]; 13 July 1918 – 26 May 1955) was an Italian racing driver and twice Formula One World Champion. He was a multitalented racer who competed in motorcycle racing before switching to cars. Ascari won consecutive world titles in 1952 and 1953 for Scuderia Ferrari. He was the team's first World Champion and the last Italian to date to win the title. This was sandwiched an appearance in the Indianapolis 500 in 1952. Ascari also won the Mille Miglia in 1954. Ascari was noted for the careful precision and finely-judged accuracy that made him one of the safest drivers in a most dangerous era. Ascari remains along with Michael Schumacher Ferrari's only back-to-back World Champions, and he is also Ferrari's sole Italian champion.

When Alberto was a young child, his father, Antonio, who was also a famous racing driver, died in an accident at the 1925 French Grand Prix. Alberto once admitted that he warned his children not to become extremely close to him because of the risk involved in his profession. So this proved when he was killed during a test session for Scuderia Ferrari at the Autodromo Nazionale Monza. Ascari was notoriously superstitious and took great pains to avoid tempting fate. His unexplained fatal accident – at the same age as his father's, on the same day of the month and in eerily similar circumstances – remains one of Formula One racing's great tragic coincidences.

Ferrari Lampredi engine

Aurelio Lampredi designed a number of racing engines for Ferrari. He was brought on to hedge the company's bets with a different engine family than the small V12s designed by Gioacchino Colombo. Lampredi went on to design a number of different Inline-4, Inline-6, and V12 engines through the 1950s, and it was these that would power the company's string of world championships that decade. All were quickly abandoned, however, with the Dino V6 and V8 taking the place of the fours and sixes and evolution of the older Colombo V12 continuing as the company's preeminent V12.

List of most expensive cars sold at auction

This is a list of the most expensive cars sold in auto auctions through the traditional bidding process, that of those that attracted headline grabbing publicity, mainly for the high price their new owners have paid.

August 2018 Ferrari 250 GTO (number 23) auctioned for $48.4 million.

June 2018: A 1963 Ferrari 250 GTO, known as the Holy Grail model, won the Tour de France in 1963, changed hands for a world record US$70 million (not auction). It is a 174 mph road-legal racing car and one of only 36 built between 1962 and 1964. It was purchased by an American businessman.

A 1962 Ferrari 250 GTO, serial number 3413GT, sold at RM Sotheby's Auction on August 25, 2018 for US$48,405,000 (including buyer's premium). This broke the record previously held by another 1962 Ferrari 250 GTO, serial number 3851GT, which sold for a then-record $38,115,000 (including buyer's premium) at Bonham's Quail Auction on August 14, 2014. While collectible cars have been sold privately for more, this is the highest price ever paid for a car at a public auction.The 1904 Rolls-Royce 10 hp Two-Seater is currently listed on the Guinness World Records as the most expensive veteran car to be sold, at the price of US$7,254,290 (equivalent to $8,765,000 in 2018), on a Bonhams auction held at Olympia in London on December 3, 2007.This list only consists of those that have been sold for at least $4 million in auction sales during a traditional bidding process, inclusive of the mandatory buyers premium and does not include private, unsuccessful (failing to reach its reserve price, incomplete) and out of auction sales.
