Lotus Elise: Road and Track: Get a Grip

updated November 2003

The Results

Buttonwillow Raceway Par

Two sections of Buttonwillow Raceway Park's East Loop were chosen for analysis: An increasing-radius hairpin and a quick right/left that tests a car's transitional composure and lateral grip. The track is run clockwise. Only the best segment times for each car are reported.

Note that for the Hairpin Turn analysis below, the speed at the end of the straight (6 )is taken at the braking point leading into the Transition Segment.

Hairpin Turn

The Hairpin of Buttonwillow’s East Loop is made tricky by a left-hand kink that occurs in the braking zone immediately preceding the increasing-radius right-hander. Exit speeds are largely influenced by vehicle power.

BRYAN HERTA'S COMMENTS
BMW M3 Coupe
I’d like to see it have a little more grip coming off the corner where I can really put some of that M power down to the ground.
Chevrolet Corvette Z06
I don’t feel like I can brake as late as I want to going into the corner. It turns in fairly well. It is a lot of fun accelerating off the corner.
Ferrari 360 Modena
It is quick, though it doesn’t have an over-whelming amount of power. The tight suspension gives you a lot of feedback.
Lotus Elise
The brakes are easy to modulate before turning in. The front tucks in nicely. I have enough grip to go faster if I had more power.
Mazda MP3
The car picks up some understeer and a little wheelspin. I would like to see a little more ride and damping control.
Mitsubishi Lancer Evolution VII
This is one place to me where it still feels like a front-wheel-drive car. I pick up that power understeer.
Porsche Boxster S
Once the car starts to understeer, it is locked in that mode and I can't balance it the way I want.
Porsche 911 Turbo
It has a lot of power and it's a fast car. There is a lot of understeer through the hairpin and on-power coming off.

Transition Segment

The Transition Segment requires the driver to compromise the ideal line in the right-hander to get the car up properly for the more important left turn.

BRYAN HERTA'S COMMENTS
BMW M3 Coupe
To drive this car hard, I have to accept the fact it needs to be sideways. It is almost a rally style of driving.
Chevrolet Corvette Z06
The steering has a positive turn-in and nice feedback. The suspension has a lot of movement and feels soft.
Ferrari 360 Modena
The car’s suspension gives you feedback early and it is more reactive to driver input.
Lotus Elise
I can carry a lot of speed into the corner, but once I start to scrub it off, I don’t have enough power to pull through.
Mazda MP3
Once the car loads down and I try to build speed, it has no problem accom-modating. It has more grip than power.
Mitsubishi Lancer Evolution VII
The same thing that helps the car to have positive turn-in also makes it good for transitioning from one direction back to the next.
Porsche Boxster S
The car carries some understeer on power, which is a nice tendency when I am coming off the corner.
Porsche 911 Turbo
Definitely a car that’s loose on entry and then has too much understeer on exit.
