Lotus is rightly happy 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 relating to the query of the place it will get its engines. The record of earlier suppliers consists of Ford, Renault, GM, Rover, Honda, and Toyota. Now that record 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 under the present 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 typical 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 automotive and 3212 kilos for the three.5. The corporate says a brand new cast-aluminum rear subframe is accountable 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 completely different persona. The AMG engine has big muscle however feels much less refined than the supercharged V-6. At low rpm, there may be noticeable turbo lag, and even at greater revs, it takes a few beats for enhance to construct in response to sudden accelerator inputs. The inline-four can also be louder than the V-6, with an exhaust observe that turns gravelly at greater speeds and wider throttle openings, overlaid by loads of induction noise and whistle from the turbocharger. All of this provides to the joy, if not the sense of refinement. After 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 purposes, the dual-clutch gearbox shifts rapidly and close to seamlessly, altering gears way more rapidly 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 in response to which of the Emira’s dynamic modes is chosen. However even within the softest Tour setting, the system kicks down aggressively underneath 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 pleasurable, with pleasingly solid-feeling steel shift paddles behind the steering wheel. When the gearbox’s digital mind anticipates a shift, gearchanges are delivered nearly 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 larger confusion. The principle gear selector at all times defaults to a central place and requires double inputs to vary 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 identical two-stage course of, which was mildly irritating.

After 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 Observe modes, left-foot brake from a standstill, ground the accelerator, and launch the brake to launch the automotive. Lotus says the four-cylinder Emira has a high velocity 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 much like that of the V-6, delivering the kind of dynamic purity Lotus is most well-known for. The Emira makes use of electrohydraulic steering somewhat than full electrical help and employs passive somewhat than adaptive dampers. Consumers of the First Version automotive will be capable of choose from two completely different chassis tunes: the firmer Sport or the softer Tour. Our pattern automotive 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 take a look at monitor, the mixture was sensible, delivering big grip and minimal understeer. Lotus engineers are rightly happy 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 occurred 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 true world, impressively sustaining order over high-speed ridges and compressions however with experience high quality turning 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 provided by the hydraulic help. Given the elasticity that has characterised lots of our favourite Lotus fashions over time, the Sport chassis feels slightly too uncompromising.

A lot else is worthy of reward. The Emira’s cabin is way classier than that of any earlier Lotus sports activities automotive, 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 snug 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 appears to be like as if there needs to be area for one, as there may be within the Porsche 718 Cayman.

Point out of the Emira’s most evident rival brings us to the query of cash. In reality, selecting the four-cylinder Lotus won’t save a lot over the V-6. Within the U.S., the absolutely loaded First Version, as pushed right here, is about to value $99,900 earlier than the as-yet-undetermined vacation spot value is added; the corresponding V-6 First Version is priced at $105,400. Each are considerably dearer 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 know the way less expensive it will likely be, however will definitely value greater than the $77,100 we reported again in 2021, earlier than manufacturing delays pushed again the Emira’s U.S. launch date.

We are able to additionally anticipate extra highly effective four-cylinder variations to comply with, with Lotus insiders admitting that the AMG engine will finally turn out to be the only Emira powerplant.
