A few questions have come up about traction control, sport mode versus sports suspension and what the Track mode in the Drivers Pack does. Here's an overview and links to more details.
First, to clear up one area of confusion. The Emira has two suspension options, Touring and Sports. There are also two (of four) Drive modes called Touring and Sport. Although confusingly these use the same naming, suspension and driving mode are completely separate. The suspension is passive and switching the driving mode doesn't change anything about the suspension.
If you're familiar with the Evora, Exige V6 or post-2011 Elise models with Sport Pack then you may know something about Lotus Dynamic Performance Management or DPM. On those cars it's seen as a "Sport" and "Traction Control" button or as a switch with Tour, Sport and Race settings.
DPM will be a feature on all Emiras regardless of engine, transmission or suspension choices. It includes three modes: Tour, Sport and Off. The extra "Track" drive mode is included as part of the Drivers Pack, which is bundled with the other packs on the First Edition cars. Some features of DPM, notably Launch Control, are only available on auto and DCT transmissions and not on the manual.
The Drive Mode switch is located on the driver's side just ahead of the gear selector:
The driving mode affects the following attributes:
Turning everything off will require signing a disclaimer, passing the Lotus Driving Academy and holding down several buttons in a complicated sequence while saying three times "I won't sue Lotus if I crash" Only kidding! It will require a further long hold on the mode button and lots of warning lights.
Turning off the ignition will revert to Tour. This will be annoying for some people, who would like to leave the car in Sport as the default. The muted exhaust note on startup will soon remind you to flick the mode switch
Here's what happens in each of the driving modes.
1. TOUR
2. SPORT
3. TRACK (for cars with Drivers Pack, including First Edition)
4. OFF
The DPM system has been developed jointly by Lotus and Bosch over many hours of development and testing. Tour is intended to keep you safe in almost all road conditions without intervening in an intrusive manner during regular driving. If you hit a patch of oil on a roundabout exit while trying to boot it then it'll give you a decent chance of avoiding a slide or spin. Sport gives the exhaust a chance to sing at lower revs and will allow some sideways action before helping you out. You also get launch control.
Track mode (Race mode on the V6 Exige) is basically witchcraft: it allows you to bury the throttle as you get to the apex of a corner and the system will work out how much torque can be applied without breaking traction or oversteering. On a typical UK track this can save you 0.5-1.0s per lap depending on your level of talent and the track conditions.
To learn more about DPM here is a link to a great article on The Lotus Forums about DPM on the V6 Exige from 2015 by Lotus Vehicle Dynamics Manager Ross Restell. This includes video footage of a V6 Exige being driven round the Lotus Hethel test track in each of the driving modes:
This write up is based on features for UK-spec cars. I've no info suggesting there are changes for other markets but it's possible some local restrictions may apply. For example exhaust valve opening may be more restricted- although the defaulting to Tour on startup should satisfy most requirements.

The driving mode affects the following attributes:
- Engine maximum rev limit
- Throttle progression
- Exhaust valve behaviour at idle and when driving
- Launch control (auto and DCT only)
- DPM characteristics - more on this below

Here's what happens in each of the driving modes.
1. TOUR
- Engine maximum rev limit: normal
- Throttle progression: normal
- Exhaust valve behaviour at idle and when driving: closed at idle, opens at high throttle load or above 4000rpm
- Launch control (auto and DCT only): not available
- DPM characteristics: Understeer Recognition on, managed Slip Threshold
2. SPORT
- Engine maximum rev limit: +200rpm
- Throttle progression: increased
- Exhaust valve behaviour at idle and when driving: open at idle (yay!), opens from low throttle load/rpm and is fully open above 3000rpm
- Launch control (auto and DCT only): available
- DPM characteristics: Understeer Recognition reduced, increased Slip Threshold and increased yaw angle available
3. TRACK (for cars with Drivers Pack, including First Edition)
- Engine maximum rev limit: +200rpm
- Throttle progression: optimum
- Exhaust valve behaviour at idle and when driving: open at idle +200rpm, opens from low throttle load/rpm and is fully open above 3000rpm
- Launch control (auto and DCT only): available
- DPM characteristics: Understeer Recognition off, ESP intervention level increased to high, traction control system calculates available grip and optimises torque to maintain grip and minimise understeer
4. OFF
- Engine maximum rev limit: +200rpm
- Throttle progression: optimum
- Exhaust valve behaviour at idle and when driving: open at idle +200rpm, opens from low throttle load/rpm and is fully open above 3000rpm
- Launch control (auto and DCT only): available
- DPM characteristics: traction control and ESP completely switched off

TLF on DPM - TLF - Everything Lotus
Lotus introduced their cutting-edge Dynamic Performance Management system to the world with the launch of the Exige V6 in 2012. Developed jointly with Bosch at huge cost, it was immediately one of the most advanced systems of its kind. 3 years later, it still is. The 2006 Elise Sports Racer was...
