Zytek Z11SN was introduced in 2011

Zytek Engineering, founded in 1981, has a long history of developing engines and racing cars, including several Le Mans Prototypes (04S, 06S, 07S, 09SC). In 2011, due to new LMP regulations, the Zytek 09SC became the LMP1 car, so the company decided to develop a new car for LMP2 class.

Zytek made a deal with Nissan to use their VK45DE engine from GT-R model. It was a 4.5-litre V8 naturally aspirated engine which produced about 450 hp. The carbon-fibre composite monocoque chassis weighed 900 kilos.

In 2011, the British team Greaves Motorsport was a sole entry with Zytek Z11SN in the Le Mans Series, in a fact they had a Zytek 07S chassis converted to Z11SN. Other teams were running Oreca 03-Nissan, HPD ARX-01d, MG-Lola EX265, Lola B11/40 or Norma M200P prototypes.

The #41 Zytek Z11SN scored an immediate success, winning the season-opening race (6 hours of Castellet), driven by Karim Ojjeh, Gary Chalandon and Tom Kimber-Smith. Ojjeh and Kimber-Smith scored two more wins (Imola and Silverstone), partnered by Olivier Lombard. At the end of the season, Greaves Motorsport won the Le Mans Series LMP2 championship, with Karim Ojjeh and Tom Kimber-Smith taking drivers’ title.

The second team with Zytek Z11SN was Jota Sport. Greaves Motorsport finished third in the final standings, with Alex Brundle and Tom Kimber-Smith participating in all three races of the season.

At 2012 Le Mans 24h race, Greaves Motorsport participated with two cars (#41 and #42), Jota  Sport fielded one car (#38).

They finished 8th in class, whilst the #41 car finished fifth, and the Jota Sport entry failed to finish.
