Initialize val on a scalatest fixture

I'm writing my first Funspec and want to use the same fixture for several tests, but still want to use a new instance on each one. For that I use the BeforeAndAfter trait. My problem is I don't know how to refer initialization of the object under test to the before method and still store it in a val to make it final. The current looks like: 

class CarTest extends FunsSpec with BeforeAndAfter{

  var car:Car = _

  before { 
      car = Car("BMW i3")
  }

  describe("A car") {

     it("can accelerate") { //do some stuff with car }

     it("can break") { //do some other stuff with car}

  }
}

So, the question is: Is there some way to make car a val and still get it initialized before each method with ScalaTest?

You could try using a fixture like so:

import org.scalatest.FunSpec
import org.scalatest.BeforeAndAfter
import org.scalatest.fixture

case class Car(model:String)
class CarTest extends fixture.FunSpec{

  type FixtureParam = Car
  def withFixture(test: OneArgTest) {
    val car = Car("BMW")
    test(car)
  }

  describe("A car") {

     it("can accelerate") { car =>

     }

     it("can break") { car =>

     }
  }
}
