BUZZ Car Madness continues with the bottom half of the Powerhouse Bracket. As you know, the 82nd Annual Geneva Motor Show is currently underway and so is the NCAA Men's Basketball Tournament. The CarBuzz team is, in true automotive nerd fashion, carrying out the tournament ourselves - except instead of college teams we are using cars that made their debuts at the Swiss show. Our 32-car single elimination knockout tournament features seeded teams based on amount of coverage generated, power, performance and relevance.

There are two brackets: the Powerhouse bracket, consisting of cars with exceptional performance and luxury, and the Mid-Major bracket consisting of economy and the more pedestrian production cars. We will bring you four match-ups a day until only one car is left. As a quick recap, in the top half of the Powerhouse bracket the Ferrari F12berlinetta, Pagani Huayra Carbon Edition, Gumpert Apollo R and Bugatti Vitesse Roadster all won their respective matches. Check out part 1 to read about the match-ups in more detail. Here is the bottom half of the Performance Bracket:

Powerhouse Bracket - Game 5: #6 Seed Brabus Bullit C-Class Coupe vs. #11 Seed Lotus Exige S Roadster The Exige S Roadster marks Lotus' fastest-ever soft-top. The 345hp 3.5-liter V6 engine allows the British convertible to hit 60mph from rest in only 3.8 seconds and reach a top speed of 145mph. The Lotus was lucky to make it into this half of the bracket, however fast roadsters made a habit of sneaking in though it gets ambushed by the only tuned model to make the bracket, the Brabus Bullit C-Class Coupe. Tuners don't qualify for this tournament, but Brabus' work was so thorough we say it makes the grade as a unique enough car of its own.

The BUZZ, like the NCAA, works in mysterious ways. The 800hp Bullit blasts off the line with 800hp and 811 lb-ft of torque for a 0-62mph sprint of 3.7 seconds and to 124mph in 9.8 seconds. It can do 230mph, totally obliterating the Exige S Roadster for looks, power, performance and coverage. Winner: #6 Seed Brabus Bullit C-Class Coupe

Powerhouse Bracket - Game 6: #3 Seed Lamborghini Aventador J vs. #14 Seed Roding 23 Roadster In the NCAA tourney, #3 Georgetown vs. #14 Belmont parallels this matchup perfectly. Yea, Belmont looks great against Atlantic Sun Conference competition but put them up against a Big East powerhouse like Georgetown and they are pretty much done and dusted. The Aventador J features a wicked design and, though not a perfect ride by any stretch (sans windshield), will still easily outmatch and outclass the Roding Roadster any day.

The Roding 23 combines a light 2,094lbs weight with a BMW-sourced 320hp 3.0-liter 6-cylinder engine for a fast 0-62mph time of 3.9 seconds and a great driving experience. The Aventador J runs on the infamous 6.5-liter V12 with 700hp, guaranteed to give a once-in-a-lifetime experience. Fitting, since it's a one-off. The world loves a new Lambo and we already have plenty of fun little roadsters roaming around the roads and tracks. Winner: #3 Seed Lamborghini Aventador J

Powerhouse Bracket - Game 7: #7 Seed GTA Spano vs. #10 Seed 2013 BMW M6 #7 vs. #10 seeds are usually close games with the winner being decided in the last minute. This is unsurprisingly the same, as the 840hp 8.3-liter V10-boasting GTA Spano takes on the ever popular and well regarded BMW M6. The new 2013 M6 runs on a 550hp 4.4-liter bi-turbo V8 and boasts a 0-62mph time of 4.2 seconds and can hit an electronically-limited top speed of 155mph. The GTA Spano proves to be Spain's pride and joy with a 2.9 seconds 0-62mph time and a top speed of 217mph.

The BMW M6 has a loyal following (including all the way to the higher-ups of the CarBuzz offices), but even if you take its electronic limiter off, you 'only' get a top speed of 189mph. Jumping on the GTA bandwagon the CarBuzz staff goes, and the M6, though a much more well-known and mainstream car, gets knocked-off by the boutique automaker's performance and power in the last minute. Oh, and it doesn't look half bad either. Winner: #7 Seed GTA Spano

Powerhouse Bracket - Game 8: #2 Seed 2013 Koenigsegg Agera R vs. #15 Seed Rolls-Royce Phantom Series II The 2013 Koenigsegg Agera R holds the 0-186mph-0 record and now the Swedes are claiming their supercar will break the Bugatti Veyron SuperSport's record for fastest production car in the world with a blistering 273mph. The impressive 5.0-liter twin-turbocharged V8 has been revised for more power and runs on either E85 biofuel or with regular pump fuel. With the latter, it cranks out a street-shaking 1,140hp.

The Agera R looks incredible in matte blue and is one of the most talked about cars of the 2012 Geneva Motor Show. The Rolls-Royce Phantom Series II has a few new features like a one-piece grille, new rear bumper and a range of 21-inch wheels. The interior is luxurious, the 6.75-liter V12 engine runs a bit cleaner and it is more efficient than last year's edition. In comparison... well, there is no comparison. Agera R in a landslide like Ohio State against Loyola - the starters chill on the bench and rest up for the GTA Spano in the next round. Winner: #2 Seed 2013 Koenigsegg Agera R
