The cars transformed by a new engine

We each cognize of cars which were fitted with an outstanding motor close from the start.

If you can’t instantly bring 1 to mind, the Bugatti Chiron is simply a bully example. There are besides galore cars which were much oregon little mean successful their archetypal forms but became more desirable successful 1 mode oregon different due to the fact that a caller motor was added to the range, oregon due to the fact that an existing motor became disposable successful a importantly altered form.

Here are 28 models which we judge are portion of the 2nd category, listed successful alphabetical order.

AC Ace

The AC Ace roadster was introduced successful 1953 and was fitted with respective engines during its accumulation run, the astir almighty being a 2.6-litre Ford straight-six. Its handling made it an effectual road-legal contention car, but implicit successful Texas Carroll Shelby (1923-2012) reckoned it would beryllium amended if it had a batch much power.

Rather than dismissing this thought and moving connected to thing else, helium created the Cobra, a reworked Ace with a Ford Windsor V8 engine initially measuring 4.3 litres and later 4.7. The Cobra proved to beryllium a mighty car successful racing, adjacent much truthful erstwhile it went into a caller procreation with a 7.0-litre Ford FE V8 under the bonnet.

Alpine A110

The archetypal A110 (not the existent exemplary launched successful 2017) was initially powered by Renault’s small Cléon-Fonte engine. This was aboriginal replaced by the larger Cléon-Alu, which had made its debut successful the Renault 16.

It’s hard to ideate the 16 being an effectual contention car, but its motor turned the A110 into a world-beater. In 1973, Alpine thrashed the absorption successful the inaugural World Rally Championship, winning six rounds and finishing the play with 147 points to Fiat’s 84 and Ford’s 76.

Audi A4

Audi has a batch of past successful this area. Most of its models person high-performance S and –  much excitingly – RS derivatives whose engines are acold much almighty than those successful the regular versions.

The A4 is simply a lawsuit successful point. Its RS 4 equivalents person ever had splendid engines. Perhaps the finest, and surely the best-sounding, was the screaming 4.2-litre V8 besides utilized successful the Audi R8. It produced implicit 400bhp, good successful beforehand of what could beryllium expected from immoderate different A4.

Audi Q7

Every Q7 is an imposing beast nary substance what powers it, but Audi went to caller and unexpected levels erstwhile it fitted the ample SUV with a 5.9-litre diesel V12. This engine, which has ne'er been utilized successful immoderate different accumulation car, produced 493bhp, which was capable to propulsion the 2635kg Q7 from 0-62mph successful an astonishing 5.5 seconds.

Fortunately, the brakes and suspension were up to the task, but acceleration similar this was inactive exhilarating oregon – depending connected your temper – alarming. And it didn’t travel cheap. Priced conscionable abbreviated of £100,000 successful the UK, the 6.0 V12 TDI, arsenic it was branded, outgo astir £40,000 more than the adjacent astir costly Q7. Data suggests that 21 reside connected British roads today.

BMW M3

Almost by definition, each M3 has had an motor which transforms it into thing rather antithetic from the regular BMW 3 Series. This was peculiarly existent of the procreation sold betwixt 2007 and 2013, which was powered by the 4.0-litre (and, for the GTS variant, 4.4-litre) S65 V8.

A aggregate grant winner, the S65 made this M3 the archetypal to nutrient implicit 400bhp successful modular form. It wasn’t the lone V8 utilized successful an M3, due to the fact that a tiny fig of earlier cars were fitted with 1 too, but it was the lone motor of this benignant utilized for each illustration successful immoderate generation.

Cadillac CT6

In astir forms, the CT6 was a full-size luxury saloon. The CT6-V was that too, but it was besides a precise awesome performer acknowledgment to its 550bhp 4.2-litre V8 engine, commonly known arsenic the Blackwing. It was besides disposable successful the CT6 Platinum, producing 500bhp.

These cars were sold lone successful the 2019 exemplary year. The full CT6 scope was discontinued soon afterwards, partially owed to mediocre income and partially due to the fact that the Detroit-Hamtramck works wherever each mentation was built was retooled to nutrient electric vehicles instead. The Blackwing sanction has been utilized again for the astir almighty versions of the CT4 and CT5, but neither of these is fitted with the Blackwing engine.

Chevrolet Corvette

Since the Corvette is 1 of the astir fashionable sports cars successful history, it seems unusual present that the first-generation mentation did not merchantability astatine each good erstwhile it was introduced successful 1953 with a straight-six engine. Two years later, it became disposable with the caller Chevy Small Block V8, primitively successful 4.3-litre signifier but aboriginal extended archetypal to 4.6 and aboriginal to 5.4 litres.

It was astir arsenic if this was what the American nationalist had been waiting for. Corvette income roseate dramatically, and a car which mightiness person been abandoned astatine an aboriginal signifier remained successful accumulation until 1962. Six decades later, its latest descendant is inactive doing well, and inactive powered by a V8 engine.

Dodge Challenger

The existent Challenger (the 3rd chiseled exemplary to carnivore that sanction successful implicit fractional a century) has been sold successful respective rather startling forms, with tremendous powerfulness outputs. Even successful that context, the SRT Demon variant, sold lone successful the 2018 exemplary year, is outstanding.

Its 6.2-litre supercharged V8 motor is the astir almighty ever fitted to immoderate road-legal Dodge, oregon so immoderate Chrysler. On regular 91-octane petrol it produced 808bhp, but with the optional Demon Crate package and moving 100-octane contention substance its output reached 840bhp. The little fig has much oregon little been equalled by the existent Challenger SRT Super Stock, but that car has somewhat little torque.

Fiat 500

The 500 was primitively disposable with a assortment of four-cylinder petrol engines. Three years aft its motorboat successful 2007, Fiat added the two-cylinder TwinAir, the archetypal motor designed from the commencement to usage the singular MultiAir exertion which had antecedently been added to existing units.

Getting anyplace adjacent the authoritative fuel consumption figures was rather a challenge, and determination was a batch of vibration until Fiat decided to adhd a dual-mass flywheel. But the popularity of the 500 has ever been owed to its cuteness much than thing else, and with the TwinAir purring distant it sounded arsenic cute arsenic it looked.

Ford Cortina

Most first-generation Cortinas were powered by either 1.2- oregon 1.5-litre versions of the pre-crossflow Ford Kent engine. In 1963, a twelvemonth aft accumulation began, the car was transformed by a caller powerfulness source, resulting successful the epoch-making Lotus Cortina.

In its nether regions, this motor was fundamentally the aforesaid arsenic a Kent, but it had a wholly antithetic cylinder head. Known arsenic the Lotus Twin Cam, it had made its debut the erstwhile twelvemonth successful the Elan sports car. For the archetypal time, present was a Cortina with a powerfulness output of over 100bhp. Further modifications brought large occurrence successful racing and rallying, successful summation to the modular car’s entreaty arsenic the 1960s equivalent of a hot hatch.

Ford Escort

As with the Cortina, the Lotus Twin Cam motor turned the mainstream first-generation Escort into thing altogether much special, but the barroom was raised overmuch higher erstwhile Ford launched the Cosworth BDA-powered RS1600 successful 1970.

Like the Twin Cam, it was based connected the Kent engine, and successful modular signifier it wasn’t overmuch much powerful. However, with four valves per cylinder it was acold much responsive to tuning, with the effect that the Mk1 Escort became 1 of the large rally cars of the aboriginal to mid 70s. Even today, proceeding a afloat tuned RS1600 screaming done a wood signifier is simply a memorable experience.

Ford Sierra

The mid-sized European Ford betwixt the Cortina and the Mondeo was disposable successful its earlier days with a assortment of engines, nary of them peculiarly melodramatic with the imaginable objection of a ample V6. The game-changer was the 2.0-litre four-cylinder portion which powered the Sierra RS Cosworth from 1986 onwards.

At its heart, it was rather humble, being based connected the well-established Pinto engine. A turbocharger and a 16-valve cylinder caput made rather a difference, though. Even successful its slightest potent signifier it produced implicit 200bhp, which nary different Sierra motor could adjacent approach. Further modified for contention use, it could scope outputs connected the acold broadside of 600bhp.

Honda Civic Type R

Honda has been producing Type R variants of its Civic since 1997, and since 2001 they person each been powered by a 2.0-litre engine. For 15 years, these were known for their singular power, their quality to rev good beyond 8000rpm and a definite deficiency of oomph earlier the VTEC adaptable valve timing switched from tea-with-the-vicar to the-zombies-are-coming mode.

Honda changed the crippled wholly successful 2015 erstwhile it added a turbocharger. The motor was present constricted to a comparatively humble 7000rpm, but abruptly determination was plentifulness of mid-range power, and the highest fig changeable up to 306bhp. After immoderate mild tweaking, it was raised further to 316bhp.

Lancia Thema

The Thema was a luxury saloon based connected the aforesaid level besides utilized for the Alfa Romeo 164, Fiat Croma and Saab 9000. Two years aft it was launched, Lancia added an outstanding mentation called the 8.32, named aft the fig of cylinders and valves successful its engine.

At 2.9 litres, this wasn’t rather the largest portion fitted to the Thema, but it was by acold the astir powerful. Derived from the Ferrari Dino V8, it produced 215bhp, a afloat 40bhp much than the 3.0-litre Alfa Romeo V6 which it demoted to 2nd spot successful the range.

Lotus Europa

Launched successful 1965, the Europa was a precise aboriginal illustration – though by nary means the archetypal – of a mid-engined road-going sports car. To statesman with, it was powered by the Cléon-Alu motor from the Renault 16, and besides utilized that car’s transaxle which, dissimilar immoderate transmission disposable from accustomed supplier Ford, could easy beryllium adapted to suit the mid-engined layout.

Lotus continued utilizing the transaxle done the Europa’s accumulation life, but it yet swapped the motor for its ain Ford-based Twin Cam. Power outputs accordingly changeable up, initially to 105bhp and aboriginal to 126bhp, giving the Europa acold much straightline show than it had started retired with.

Mazda CX-7

Replacing a almighty petrol motor with a overmuch little almighty diesel whitethorn look similar a backward step, but successful this lawsuit it was the close happening to do. The CX-7 SUV was initially disposable lone successful the UK with the 256bhp 2.3-litre petrol motor besides recovered successful the high-performance Mazda3 MPS and Mazda6 MPS. Everyone knew this was a atrocious thought – including, they would softly admit, Mazda’s British representatives.

Two years later, successful 2009, that motor was dropped successful favour of a 2.5-litre diesel. The terms went up, and the powerfulness output dropped by a startling 85bhp, but the CX-7 was present taxable to £190 little Vehicle Excise Duty each twelvemonth and was, according to the authoritative substance system figures, 10mpg little thirsty. A antecedently astir unsellable conveyance had present been transformed into thing that suited its people customers.

Mercedes A-Class

The third-generation A-Class was mostly disposable with a assortment of engines with powerfulness outputs successful the 100-210bhp range. One twelvemonth aft launch, though, Mercedes introduced the four-wheel thrust A 45 AMG variant (subsequently renamed Mercedes-AMG A 45).

The quality this made to the car’s straightline show was phenomenal. The highest powerfulness output successful the scope had present changeable up by 70% to 355bhp, and that was lone the start. Following a revision, it roseate inactive further to 376bhp. Today’s fastest A-Class has a antithetic but conceptually akin motor which produces 416bhp.

Mercedes R-Class

In a spectacular illustration of what we called “Mercedes’ every-engine-in-everything merchandise planning,” the R-Class became disposable with a 503bhp 6.2-litre V8 motor a twelvemonth aft its launch.

As a ample luxury MPV, it was good suited to almighty engines, but this was a full caller shot game. The large V8 produced 503bhp, which was acold much than anyone needed – or, apparently, wanted. Sales were minimal, and the R 63 AMG, arsenic it was called, disappeared from the terms lists precise quickly.

MGB

The MGB roadster was launched successful 1962, and a coupe mentation called the MGB GT came on 3 years later. In an effort to make a high-performance variant, MG archetypal fitted a 2.9-litre straight-six motor and called the effect MGC, but this was unsatisfactory and was abandoned aft conscionable 2 years.

A 2nd effort followed successful 1973. This time, MG created the MGB GT V8 by fitting the 3.5-litre Buick-derived Rover motor into the coupe. It didn’t past overmuch longer than the MGC had, but by wide consent it was a acold superior car.

Renault 6

This was a precise mild but inactive valid illustration of the rule we’re discussing. The 6 was designed arsenic an upmarket alternate to the Renault 4 which was fitted astatine its motorboat successful 1968 with the aforesaid contiguous post-War Billancourt engine, adjacent though the larger and much almighty Cléon-Fonte had been disposable for six years.

In 1970, Renault did the close happening and added the Cléon-Fonte to the range. With this engine, the 6 inactive wasn’t particularly speedy – and didn’t truly request to beryllium – but it was astatine slightest acceptably so. As we said successful a 1974 roadworthy test, determination was “no uncertainty that Renault’s engineers got their sums precisely right” astatine the 2nd attempt.

Renault Clio Renaultsport

The archetypal fewer versions of Renault’s hottest Clio were each powered by a high-revving, naturally-aspirated 2.0-litre engine. This argumentation changed dramatically successful 2013, erstwhile Renault switched to a 1.6-litre turbo co-developed with Alliance spouse Nissan and producing akin powerfulness (197bhp).

There was nary uncertainty that the Clio’s quality had been transformed. The question was whether this was a affirmative oregon a antagonistic move. There were those who felt the superior mid-range performance was a large improvement, but we reckoned that “all the erstwhile car’s impish zip has been sucked mercilessly from the bone”.

Saab 96

Saab fitted thing but two-stroke engines to its cars each the mode from the motorboat of the 92 successful 1949 until astir halfway done the accumulation beingness of the 96 (the 92’s 2nd successor) 18 years later. At this point, it switched to a four-stoke V4 developed by Ford of Germany.

It wasn’t 1 of the world’s large engines, but it was much almighty than thing Saab had utilized successful the past. Crucially, it besides didn’t dependable similar a wasp trapped successful a tin tin oregon emit clouds of smelly bluish smoke. The 96 lasted until 1980, which it surely wouldn’t person done if Saab had persevered with the two-stroke.

Sunbeam Alpine

The communicative of the Sunbeam Tiger astir precisely mirrors that of the somewhat earlier AC Cobra. Both cars were suggested by Carroll Shelby, who (in the lawsuit of the Tiger) thought determination was thing incorrect with Sunbeam’s Alpine sports car that couldn’t beryllium fixed by giving it much power.

As with the Cobra, the Alpine was converted to judge the Ford Windsor motor (4.3 litres astatine first, aboriginal 4.7) and fixed a suitably assertive name. This time, though, determination would beryllium nary progression to a larger Ford V8.

Vanden Plas Princess

Of the respective cars known arsenic Vanden Plas Princess, the 1 we’re funny successful present was the large, Farina-designed saloon which was astir identical to models produced by Austin and Wolseley. All were powered by a 2.9-litre straight-six engine, but lone the Princess was taken a signifier further.

In 1964, it was fixed a caller sanction – Princess R – pursuing respective revisions, the astir melodramatic being the fitment of a 3.9-litre motor developed by Rolls-Royce. The powerfulness output jumped from astir 120bhp to 175bhp, which made the Princess acold quicker than before, though fixed the quality of the car it’s apt that much effortless high-speed cruising was considered much important than sharper acceleration.

Vauxhall Carlton

The Carlton GSi was a good car with fantabulous handling and a beardown 3.0-litre 24-valve engine. It was besides the ground of that Wagner opera connected wheels, the Lotus Carlton. Despite claims to the contrary elsewhere connected the internet, each illustration of this exemplary came disconnected the Opel accumulation enactment successful Rüsselsheim arsenic a modular GSi earlier being shipped to Lotus successful Hethel for a conversion which lasted 150 hours.

The alterations included raising the capableness of the six-cylinder motor from 3.0 litres to 3.6 and fitting 2 Garrett turbochargers. Power output accordingly changeable up from the archetypal 204bhp to 377bhp (if the engines was fed with sufficiently high-octane petrol), and the straightline show improved to specified an grade that determination were calls for the car to beryllium banned.

Volkswagen Golf R

The archetypal 2 generations of Golf R were known arsenic R32, a notation to their 3.2-litre V6 engines. They were speedy and sounded fabulous, but that motor was precise dense and mounted astir wholly up of the beforehand axle, which created large handling problems successful the archetypal version. The adjacent 1 was better, but inactive occasionally troublesome, particularly implicit a bid of closely-spaced crests.

For the procreation aft that, Volkswagen ditched the 32 portion of the sanction and fitted a turbocharged 2.0-litre four-cylinder. This was much powerful, but crucially it was besides lighter. The handling issues disappeared completely, and the R became the splendid hot hatch it should person been successful the archetypal place.

Volkswagen Passat

The Passat introduced successful 1997 was (a erstwhile proprietor writes) a worthy but not peculiarly breathtaking car disposable with engines which could mostly beryllium described arsenic straightforward – but one. This was a 4.0-litre W8, fundamentally 2 2.0-litre V4s mounted connected a communal crankcase, the lone motor of that benignant ever fitted to a accumulation car.

Available from 2001, it produced 271bhp, making it the astir almighty motor utilized successful a Passat of that procreation by implicit 80bhp. Despite its outstanding features, it sold precise badly, and the task was soon abandoned, which whitethorn person been what VW expected to happen.

Volkswagen Touareg

In different portion of extravagant motor policy, Volkswagen added a 6.0-litre W12 to the Touareg 2 years aft the big SUV was launched. This motor was astir arsenic uncommon arsenic the W8 fitted to the Passat, but was besides utilized successful the Audi A8, the Bentley Continental and the VW Phaeton.

Once again, this motor blitzed each the others successful the scope successful presumption of performance, with a maximum output of 444bhp. VW initially planned to physique lone 500 examples of this peculiar Touareg, but continued accumulation erstwhile it proved to beryllium amazingly popular.

Morris Minor

At the clip of its motorboat successful 1948, the Minor was fitted with a 918cc motor based connected a Wolseley plan which was already 20 years old. It was highly improbable that this portion would last, arsenic the car did, until arsenic precocious arsenic 1971. In fact, the alteration happened precise aboriginal successful the Minor’s career. In 1952, Morris was brought unneurotic with its erstwhile arch-rival Austin successful the British Motor Corporation.

This gave Morris entree to the caller BMC A-Series engine, which had conscionable been introduced successful the Austin A30. Despite being smaller, astatine 803cc, the A-Series had akin powerfulness to the motor it replaced, and acold much scope for development. By the extremity of Minor production, it was being utilized successful 1098cc form, and inactive had astir 3 decades much beingness near successful it.

Talbot Sunbeam

Most Sunbeams were fitted with either 1.3- oregon 1.6-litre versions of the motor utilized successful the Hillman Avenger oregon a 928cc portion derived from that of the Hillman Imp. The outlier was a 2.2-litre 16-valve Lotus motor, portion of a scope which was utilized some successful the Jensen-Healey sports car and respective models produced by Lotus itself.

With a powerfulness output of 150bhp, the Sunbeam Lotus was a formidable roadworthy car, but that wasn’t its main purpose. The thought had been to pull publicity for the marque done motorsport, and it worked. Just earlier four-wheel thrust turned the full country upside-down, the Sunbeam Lotus was competitory capable to gain Talbot the Manufacturers’ rubric successful the 1981 World Rally Championship.

Vauxhall Chevette

The Chevette was initially a tiny hatchback (though saloons and an estate followed) based connected the Opel Kadett. Nearly each mentation was fitted with a 1256cc engine, but Vauxhall, similar Talbot with the Sunbeam, decided that a much almighty mentation intended for rallying would beryllium bully for publicity.

There was nary mode that the archetypal motor would beryllium suitable for this, truthful Vauxhall took its 2.3-litre Slant-4 engine, added a 16-valve cylinder caput and enactment it nether the bonnet to make the Chevette HS (pictured). (Early rally cars were fitted with a akin caput developed by Lotus, but this was soon banned.) The aforesaid mechanical statement was utilized for the aboriginal HSR, which had respective fibreglass panels, including wide beforehand and rear wings which gave the car a precise melodramatic appearance.
