Lotus is rightly pleased with the chassis-tuning experience that has created so many positive roadgoing sports activities vehicles over the many years. But the British firm has lengthy been agnostic in terms of the query of the place it will get its engines. The checklist of earlier suppliers contains Ford, Renault, GM, Rover, Honda, and Toyota. Now that checklist has a brand new addition: Mercedes-AMG, which builds the turbocharged 2.0-liter four-cylinder that powers the entry-level 2024 Lotus Emira.

That is the M139 engine that’s utilized in fashions together with the CLA45 and GLA45, though Lotus is getting a decrease state of tune. Within the Emira hierarchy, it sits beneath the prevailing V-6—which makes use of a supercharged 3.5-liter engine from Toyota—however the hole in efficiency (additionally in worth) between the 2 variants is small. The four-cylinder makes 360 horsepower, whereas the V-6 has 400 ponies, and the smaller engine produces barely extra torque—317 lb-ft versus 310. In accordance with Lotus’s personal claims, the two.0-liter’s 4.3-second 60-mph time is only a tenth behind the V-6’s.

Complicating that comparability is the truth that the 2 engines do not share a transmission. The V-6 has a regular six-speed handbook and the choice of a six-speed torque-converter automated. The four-cylinder is paired solely with the eight-speed dual-clutch automated that is acquainted from transverse-mounted AMG powertrains. The mass of the brand new gearbox means the four-cylinder is barely lighter than the six, with Lotus claiming a 3187-pound curb weight for the two.0-liter automobile and 3212 kilos for the three.5. The corporate says a brand new cast-aluminum rear subframe is liable for 26 kilos of weight discount—or one pound lower than the distinction.

Regardless of their proximity on paper, this second Emira variant possesses a really totally different persona. The AMG engine has enormous muscle however feels much less subtle than the supercharged V-6. At low rpm, there’s noticeable turbo lag, and even at increased revs, it takes a few beats for increase to construct in response to sudden accelerator inputs. The inline-four can be louder than the V-6, with an exhaust be aware that turns gravelly at increased speeds and wider throttle openings, overlaid by loads of induction noise and whistle from the turbocharger. All of this provides to the thrill, if not the sense of refinement. Once we first drove the V-6 Emira, we reckoned that its engine lacked character. The inline-four might effectively have an excessive amount of.

As in its Mercedes functions, the dual-clutch gearbox shifts shortly and close to seamlessly, altering gears far more shortly than is feasible with the V-6’s handbook (we’ve got but to expertise the six-cylinder’s torque-converter auto). In drive, the gearbox alters its shifting technique based on which of the Emira’s dynamic modes is chosen. However even within the softest Tour setting, the system kicks down aggressively beneath modest throttle will increase, presumably to assist spin up the turbo. Sport mode brings an much more aggressive algorithm and a flat-out refusal to upshift into the tallest gears even when cruising. (And with eighth gear pulling 1500 rpm at an indicated 65 mph, the tallest gear could be very tall.)

Fortuitously, handbook gear choice is easy and satisfying, with pleasingly solid-feeling steel shift paddles behind the steering wheel. When the gearbox’s digital mind anticipates a shift, gearchanges are delivered virtually seamlessly—shifting up when accelerating or down when braking. However we did discover foibles. It was simple to hit the rev limiter when upshifting on the immediate of the digital dashboard’s upshift warning, as if the show had been lagging barely.

The transmission additionally usually grew confused when requested to ship a number of upshifts or downshifts shut collectively, with a pause that was usually lengthy sufficient to set off a second request and higher confusion. The primary gear selector all the time defaults to a central place and requires double inputs to alter gear. In drive, pushing it ahead first engages impartial; a second push ahead is required to get into reverse. Going from reverse to drive is similar two-stage course of, which was mildly irritating.

Once we lastly get to run numbers on each variants, we might be unsurprised to find that the four-cylinder is the quickest Emira, due to each its ultraquick transmission and a launch-control operate. To activate launch management in Sport or Monitor modes, left-foot brake from a standstill, flooring the accelerator, and launch the brake to launch the automobile. Lotus says the four-cylinder Emira has a prime pace of 171 mph, which is 9 mph in arrears of the V-6. Given the similarities in output, that declare might have extra to do with advertising than engineering actuality.

The remainder of the two.0-liter’s driving expertise stays just like that of the V-6, delivering the type of dynamic purity Lotus is most well-known for. The Emira makes use of electrohydraulic steering fairly than full electrical help and employs passive fairly than adaptive dampers. Consumers of the First Version automobile will be capable of choose from two totally different chassis tunes: the firmer Sport or the softer Tour. Our pattern automobile was a Sport using on the optionally available track-biased Michelin Pilot Sport Cup 2 tires rather than the usual Goodyear Eagle F1s.

On Lotus’s Hethel check observe, the mixture was sensible, delivering enormous grip and minimal understeer. Lotus engineers are rightly pleased with the stability-control tuning that has been collectively developed with Bosch. Within the Sport mode, the system permits important rear-end slip earlier than intervention, but nonetheless steps in earlier than a slide turns right into a spin. Not like the V-6, the four-cylinder Emira does not get a limited-slip differential, nevertheless it by no means felt in need of traction or self-discipline even at circuit speeds.

However most of our expertise came about on regular U.Ok. roads, the place we had been quickly wishing for the softer Tour chassis. The Sport setup feels very agency in the actual world, impressively sustaining order over high-speed ridges and compressions however with journey high quality changing into harsh at decrease speeds over poor surfaces. Rougher roads additionally resulted in a lot of steering kickback, the trade-off for the high-definition suggestions supplied by the hydraulic help. Given the pliability that has characterised lots of our favourite Lotus fashions over time, the Sport chassis feels just a little too uncompromising.

A lot else is worthy of reward. The Emira’s cabin is much classier than that of any earlier Lotus sports activities automobile, with high quality supplies and a nice-looking central show along with Volvo-sourced switchgear. The audio system is highly effective and impressively crisp by sports-car requirements, and the Emira’s seats stayed comfy after a number of hours behind the wheel. Baggage area is scant, with a tiny four-cubic-foot compartment behind the engine plus a modest quantity of area behind the seats. There is no such thing as a entrance baggage compartment, though it seems as if there ought to be area for one, as there’s within the Porsche 718 Cayman.

Point out of the Emira’s most blatant rival brings us to the query of cash. In fact, selecting the four-cylinder Lotus won’t save a lot over the V-6. Within the U.S., the totally loaded First Version, as pushed right here, is about to price $99,900 earlier than the as-yet-undetermined vacation spot price is added; the corresponding V-6 First Version is priced at $105,400. Each are considerably costlier than an equal Porsche 718—these being the $81,950 Cayman S and the $96,850 Cayman GTS 4.0. A base Emira 2.0-liter will comply with. We do not understand how less expensive it will likely be, however will definitely price greater than the $77,100 we reported again in 2021, earlier than manufacturing delays pushed again the Emira’s U.S. launch date.

We will additionally anticipate extra highly effective four-cylinder variations to comply with, with Lotus insiders admitting that the AMG engine will finally change into the only Emira powerplant.
