7 4-Cylinder Sports Cars That, Dare We Say, May Be Called Super – Jalopnik

We all have other ways of deciphering outline a supercar, however usually talking, most of us will image one thing mid-engine and technically spectacular, with a correctly highly effective engine at its disposal. Something like a V8, V10, and even V12.

There are exceptions to the rule, after all. The Lexus LFA and Mercedes-AMG SLS Black Series present that supercars might be front-engine, or a minimum of front-mid, and Ford’s 2017 GT proved a V6 engine was greater than able to changing engines with greater cylinder counts. Well, it is about time one other exception was made, for a small grouping of forward-thinking four-cylinder supercars.

Cars just like the outdated Lotus Esprit, which mixed raked styling with turbo expertise to provide a smooth coupé which might even rival Ferraris for efficiency, and Alfa Romeo’s marvelous 4C, which packs F1-grade expertise right into a four-pot-powered carbon-fiber monocoque chassis. Here are seven four-cylinder-powered fashions from throughout a long time, in chronological order from oldest to latest, that cross the road between sports activities automobile and supercar.

This fairly little sports activities coupé from the Nineteen Sixties, penned by Giorgetto Giugiaro, flies far below the radar as we speak. However, the common-or-garden 1.0-liter ASA 1000 GT started life as a possible four-cylinder Ferrari. At the tail finish of the Nineteen Fifties, Enzo Ferrari revealed plans to develop an entry-level sports activities automobile that may take its energy from a 3rd of his profitable Colombo V12 engine. He by no means introduced the design to manufacturing, however within the early Nineteen Sixties the lesser-known agency Autocostruzioni Societa per Azioni, or ASA, did.

ASA’s dinky 1000 GT boasted a spaceframe chassis cloaked in metal and aluminum bodywork. In its closing guise, the inline-4 sported a 1,032-cc capability and was fed by a pair of sidedraft Weber carburetors. It packed round 95 horsepower alongside 75 pound-feet of torque, tackled the 0-60 dash in 13 seconds, and will make all of it the way in which as much as 113 mph. Power was delivered to the wheels through a four-speed overdrive gearbox, whereas Dunlop disc brakes in all 4 corners dished out the stopping energy.

Inside, a Ferrari-like Nardi steering wheel and Jaeger devices headlined the dashboard, whereas different Prancing Horse adornments helped justify the sadly excessive asking value — an element that may ultimately be the ASA’s undoing. Essentially, the 1000 GT delivered all the pieces that is so particular concerning the raciest of ’60s Ferraris, simply in a pint-sized bundle. Genuine Colombo DNA, a placing Giugiaro design, performance-first underpinnings, and all of the cabin trimmings one would anticipate from a ’60s Lusso.

It’s inconceivable to not carry up the Lotus Esprit when four-cylinder supercars are the subject. This rakish wedge of English engineering excellence loved a prolonged profession, with two dozen variations throughout 28 years. The earlier automobiles, produced between 1976 and 1987, have been designed by Giugiaro, whereas later fashions – ’87 via 2004 — have been the work of Peter Stevens.

The earlier automobiles’ efficiency was modest. With simply 160 hp and 140 lb-ft to play with, 60 mph from a standstill could be met in 8.4 seconds, with a high velocity of 124 mph. Later revisions noticed output develop together with the inline-4’s capability, nevertheless it was when Lotus launched a boosted mill that efficiency actually caught up with the Esprit’s supercar styling. The first Turbo automobiles kicked out 213 hp alongside 200 lb-ft — sufficient to see the Lotus reduce its 0-60 time by over 2 seconds, whereas its high velocity swelled to a genuinely spectacular 150 mph.

The later Stevens-designed automobiles constructed on this success, with essentially the most potent four-cylinder automobiles delivering within the area of 300 hp alongside 290 lb-ft within the S4 S guise. By this level, 0-60 was all the way down to 4.6 seconds, and at full-chat, the four-pot Esprit knocked on the door of 170 mph. That’s not far behind what the V8-powered Ferrari 348 might do on the time, demonstrating why Lotus’ four-cylinder supercar deserves a spot on this checklist.

This is restricted to the 924 Carrera GT, as the usual 924 barely earns a sports activities automobile classification, not to mention passing for a supercar. It was powered by a van engine, and early variations did not even kick out 100 horsepower. Whether the 924 was a hit is up for debate, as whereas it was underwhelming, it offered effectively. But one factor is for positive: The Carrera GT rendition of this simply neglected coupé is a gem.

The Carrera GT (and the ever-more-hardcore GTS and GTR variants) have been based mostly on the 924 Turbo, though key tweaks have been made to see its output rise from 168 hp to 210 within the GT. It sported a top-mounted intercooler, digital ignition, and a better compression ratio, whereas GTS automobiles (identifiable by their fastened, Perspex-covered headlights) ran an additional 3.6 kilos per sq. inch (psi) of enhance. That noticed the 924 GTS ship a peak of 245 hp in street trim, or, for the uber-rare GTS variants laid out in Clubsport guise, 275.

Porsche stored the Turbo’s inside as-is within the GT, though GTS fashions had weight pulled out of them, and Clubsport automobiles sported a roll cage, too. The complete level of the Carrera GT was to compete at Le Mans — these have been homologation automobiles — and the plucky Porker truly returned a category win. So, a race automobile for the street with large, blistered arches, and over 2.5 occasions the bottom 924’s output? Sounds like a supercar to us.

It was clear to Porsche that the four-cylinder recipe had some legs, so within the Eighties, it developed the 968. Under the hood of 968 fashions sat an enormous 3.0-liter inline-4 engine that kicked out 240 horsepower. Certainly respectable, and certainly one of Porsche’s most necessary engines, however undoubtedly no supercar.

That’s the place the Turbo S variant is available in. Like with the aforementioned 924 Carrera GT, it was homologation that known as the Turbo S into being. It was immediately recognizable due to hood vents, an enlarged bumper vent, and 964-Turbo-sourced three-piece Speedline wheels. Under the hood, the addition of a water-cooled turbocharger with enhance stress set to 14.5 psi noticed output rise from 240 to 305 horsepower. That was sufficient to see the 968 deal with 62 mph from a standstill in simply 5.0 seconds, and it might handle 174 mph on the high finish.

The 968 Turbo S can also be hypercar ranges of uncommon, with solely 14 road-going examples ever produced. As a outcome, the boosted 3.0-liter engine below its hood is critically scarce, and collectors can pay loopy quantities to assert one when an instance truly seems on the market. The final to look noticed bids attain $775,000, though with an estimated value of $900,000 to $1.2 million, the present proprietor apparently values it even greater.

The sheer quantity of super-impressive expertise wrapped into the Mono is sufficient to embarrass the spec sheet of many a so-called thoroughbred supercar. The BAC Mono seats just one, nestled into the middle of a carbon-fiber tub, wrapped in graphene panels as a substitute of carbon ones. Graphene – a fabric BAC was the primary to develop to be used in a manufacturing automobile — is lighter than carbon, so 20 kilos have been shaved by making the shift. This issues on condition that the Mono solely weighs between 1,224 and 1,279 kilos, relying on the mannequin.

Then there are the Sachs suspension, AP Racing brakes, Oz Racing alloy wheels, and specifically designed Kuhmo tires. In Mono R trim, BAC tells us, its creation laps the Red Bull Ring a full 6 seconds quicker than a Ferrari LaFerrari. Forget supercar territory, this windshieldless curler coaster for the street is fast sufficient to see even essentially the most celebrated of hypercars take a again seat in its (non-existent) rearview mirror.

It could be straightforward to imagine that some hybridized turbocharged V6 or V8 lurks someplace under the Mono’s minimalist traces, however as a substitute, motivation is offered by both a 2.3-liter or 2.5-liter inline-4 engine — each naturally aspirated. Power from the smaller engine is available in at 280 horsepower, whereas the bigger brings 305 to the celebration, or 343 in “R” guise.

Much just like the BAC, however in a barely extra road-friendly method, Alfa Romeo’s little 4C boasts a formidable spec checklist, with options and parts usually extra at residence on one thing with a prancing horse on the hood. Part of the 4C’s enchantment is its low dry weight of simply 1,973 kilos, achieved utilizing a formidable unfold of light-weight supplies extra usually discovered within the supercar phase.

At the very core of its design sits a 143-pound carbon-fiber monocoque, developed utilizing F1-inspired “pre-preg” expertise – that’s, pre-impregnated with resin and a curing agent. Accompanying this tub are aluminum subframes entrance and rear, which nets the 4C extra worthwhile weight saving, as do its composite — sheet molding compound and injected polyurethane — physique panels and bumpers. Even the window glass is 10% thinner and 15% lighter than what’s typical. Alfa Romeo went to such extremes in conserving the 4C’s weight down, you’d virtually really feel unhealthy driving it after an enormous lunch.

With such a light-weight building and dinky footprint — its wheelbase measures solely 93.7 inches, though it is huge, at 73.5 inches — Alfa Romeo felt a punchy little four-cylinder was greater than as much as the duty of motivating the 4C. A turbocharged 1.7-liter inline-4 with 237 horsepower and 258 lb-ft is what the automaker opted for, which is not very supercar-like on paper, however its 4.2-second 0-60 time demonstrates simply how succesful it’s when coupled to such a well-engineered, technically spectacular chassis.

The newest four-pot sports activities automobile worthy of crossing over into supercar territory is the Lotus Emira. It arrived for the 2024 mannequin 12 months and, regardless of unique plans for it to be discontinued round 2027, new energy trains are coming the Emira’s means, which ought to see it dwell on for just a few extra years.

Those two new energy trains are but to be confirmed — reportedly, one shall be a plug-in hybrid, with the opposite an improve to the mannequin’s present Toyota-sourced V6 — however none of those is the engine within the highlight right here. Instead, it is the Emira’s entry-level turbocharged 2.0-liter Mercedes-AMG inline-4 that matches this text’s invoice.

Currently, the “four” is accessible in two states of tune: a 400-horse and a 414-horse guise, the previous within the Emira SE, the latter powering the Emira 420 Sport. For reference, the supercharged V6 kicks out 400, so it is truly the Sport’s AMG-sourced inline engine which that is most potent, regardless of its decrease cylinder depend.

The Sport’s four-pot-powered Lotus speeds to 62 mph from a standstill in 3.9 seconds and boasts a high velocity of 186 mph. It must be a riot to pilot on monitor, too, due to a decrease trip peak and vital cooling enhancements. There’s even an optionally available Lightweight Handling Pack, which sees Michelin Pilot Sport Cup 2 tires, two-way adjustable Multimatic dampers, a titanium exhaust, lighter lithium-ion battery, and carbon-fiber louvered tailgate be part of the combo. A compelling checklist of substances that actually helps the Emira be as fast because it seems to be.
