However, this engine has received “fundamental changes” for the Emira, including a new intake and exhaust, which reduces power outputs from the 382bhp and 354lb ft of entry-level AMG cars to 360bhp and 317lb ft.
An eight-speed dual-clutch automatic gearbox is fitted to the AMG unit as standard.
In First Edition trim, the AMG-engined Emira is £77,795 – £4500 cheaper than one fitted with the supercharged Toyota V6.
Deliveries of the four-pot Emira are expected to begin in the autumn and a significantly cheaper trim level – originally pitched at £59,995 but expected to cost more on arrival – will go on sale before the end of the year.
The Emira will be Lotus’s final combustion-engined series-production sports car. All new models will adopt battery-electric powertrains sourced from Lotus's Geely group parent company.
The brand is set to radically expand its EV line-up over the next few years, launching a saloon based on the new Eletre in 2024. A high-volume rival to the Porsche Macan EV is scheduled to arrive by 2028 and is expected to contribute roughly 75,000 sales a year to Lotus's overall output.
Such cars will be engineered at Lotus’s new factory in Wuhan, China. However, purist sports cars in the mould of the Emira, Evora and Elise will continue to be made in Hethel, Norfolk.
