How to print table data in Laravel 5.6?

in My Larvel 5.6 app I am working with mysql db. and in my application I have vehicle table with following columns, vehicles,

id  category  number  brand model
1   car       123     bmw   520d
2   van       258     ford  mark
3   car       256     benz  ultra
4   car       259     bmw   520d
etc

and I am going to group all models of the table and printing here as My controller,

public function modelstatic()
    {
      $models = Vehicle::groupBy('modelname')->select('id', 'modelname', \DB::raw('COUNT(*) as cnt'))->get();  

      return view('modelreports.modelstatic')->withModels($models);
    }

my printing blade file is this,

@foreach($models as $model)

@endforeach

it is printing well as

520d
mark
ultra

now I need print in-front of model name there brand name as

520d - bmw
mark - ford
ultra - benz

then how can I do this now? I have separate Models for brand and model and still there are not relationship between Modols. how can I do this, may I need relationship or may I could print brand name via vehicle table data?
