Plaintiffs lawyers who helped craft an $800 million settlement with Fiat Chrysler this year over its “EcoDiesel” vehicles are asking for $66 million more in attorney fees and costs.

U.S. District Judge Edward Chen of the Northern District of California has scheduled oral arguments Friday about whether to grant final approval of the deal, which includes a $307 million class action settlement and $400 million to federal and state regulators to resolve claims that it installed software in 100,000 vehicles nationwide to cheat emissions tests. In court papers, lead counsel Elizabeth Cabraser said the request for $59 million in attorney fees and $7 million in costs would be in addition to, and not deducted from, the settlement’s $800 million value. She said the fees were reasonable in light of the complexities of the case.
