Should Nissan and Mazda get more powerful 350Z, RX8

[Ford Capri 2.8i]

Once Nissan decided to be replaced its powerful 300bhp 300ZX Twin Turbo by a less powerful(and quite more slow as the Old Car vs New Car Top Gear comparison shows) 350Z.

And Mazda has taken a similar decision replacing the 280bhp RX-7 for a slower RX-8

Do members thing that Nissan and Mazda had to achieve higher goals such as launching about 360 bhp cars capable of challenging against the Ferrari 360, the Gallardo, the 911 GT3, the DB9, and so on?

My opinion is affirmative, for instance, for me means to save some money spending more euros in a DB9, Gallardo, and get more performances, pleasure of driving, rather than saving more money and not getting the nice sensations that give the Gallardo car segment
